DALP Code | Machine name | Category | Message | Why | Suggested Fix | Severity | Retryable | HTTP Status |
|---|---|---|---|---|---|---|---|---|
DALP-0500 | COMPLIANCE_ | domain | Compliance webhook signing secret rotation grace period expired. | The pending webhook signing secret expired before it was promoted to the active secret. | Start a new secret rotation and update the provider dashboard with the active webhook signing secret. | info | No | 410 |
DALP-0501 | COMPLIANCE_ | client | Compliance provider cannot transition to the requested state. | The provider's state does not permit the operation: it is paused, revoked or not active, its status or pending secret changed meanwhile, a secret rotation is already pending, its kind does not offer the operation, or the trusted-issuers registry refused the change. | Refresh the provider and choose an operation that matches its current state. | info | No | 409 |
DALP-0502 | COMPLIANCE_ | client | Compliance provider not found. | No active compliance provider matches the webhook URL: the provider id or URL token is unknown or wrong, the provider was revoked, or the URL names another provider kind. | Use the webhook URL the provider was given when it was created. | info | No | 404 |
DALP-0507 | WEBHOOK_ | client | Webhook replay rate limit exceeded. | The organisation used up its per-minute allowance of webhook replays or test events, or the endpoint used up its test-event allowance. | Wait the number of seconds in data.retryAfterSeconds, then send the request again. | info | Yes | 429 |
DALP-0508 | WEBHOOK_ | client | Webhook replay range is too large. | The replay range spans more blocks than one request may replay without confirmLargeRange. | Split the range into smaller ranges, or send confirm, then retry. | info | No | 400 |
DALP-0509 | WEBHOOK_ | domain | Webhook endpoint disabled. | The endpoint is disabled or its circuit breaker is open, so a replay onto it would never be attempted. | Re-enable the endpoint after fixing the delivery failure cause, or wait for its breaker to close, then retry the replay. | info | No | 409 |
DALP-0510 | WEBHOOK_ | auth | Webhook signature verification failed. | The receipt's signature does not verify against the endpoint's active or previous signing secret, its innerEventHash does not match the delivered payload, or its receipt window has closed. | Sign the receipt with the endpoint's current signing secret, hash the exact delivered payload, and send the receipt within the receipt window. | info | No | 401 |
DALP-0512 | WEBHOOK_ | client | Webhook endpoint URL is not allowed. | The endpoint URL is not a valid URL, or its host resolves to a private, loopback or link-local address, or outside the operator's target allow list when one is set. | Use a valid https:// URL whose host resolves only to public addresses, or ask an operator to admit its range. | info | No | 400 |
DALP-0513 | WEBHOOK_ | domain | Webhook endpoint limit reached. | The organisation already has 1,000 webhook endpoints that are not deleted, the most it may register. | Delete an unused endpoint, then create the new one. | info | No | 409 |
DALP-0516 | WEBHOOK_ | client | Webhook endpoint has pending delivery attempts. | The endpoint has queued deliveries, and the request changes its URL, which re-targets them, or disables it, which cancels them, without acknowledgePending=true. | Wait for the queue to drain, or re-send the request with ?acknowledgePending=true to confirm the effect on queued deliveries. | info | No | 409 |
DALP-0517 | WEBHOOK_ | client | Fat-event acknowledgement is missing required field paths. | A fat endpoint delivers unredacted personal data for its active subscriptions. Every <eventType>.<fieldPath> that the thin shape would strip must be named in fat for the resulting subscription set. The acknowledgement on this request, or the stored one when the request omits it, does not cover that set, so the platform rejected the update. | Resend the PATCH with fat listing every personal-data field that thin payloads remove for the resulting subscriptions and their retractions, in <eventType>.<fieldPath> form. The Console's switch-to-fat dialog prepares this list and records the acknowledgment. To create a fat endpoint, register it thin, then switch it with this PATCH. | info | No | 422 |
DALP-0523 | TOKEN_FEE_RATES_FROZEN | domain | Transaction fee rates frozen. | Transaction fee rates are frozen on this token's fee feature. | Leave the frozen rates unchanged or configure a different token feature. | info | No | 409 |
DALP-0524 | REQUEST_ | permission | The selected participant is not available. | The selected participant does not exist or cannot be assumed by the authenticated user. | Select an authorized participant or request an administrator grant. | info | No | 403 |
DALP-0525 | COMPLIANCE_ | dependency | Compliance provider rejected transaction registration. | The compliance provider's transaction-registration call failed before DALP could persist the transaction-id mapping. | Verify provider credentials and the submitted transaction fields, then retry transaction registration. | error | No | 502 |
DALP-0526 | WEBHOOK_ | client | Webhook endpoint not found. | No webhook endpoint with that identifier exists in the current tenant, or the endpoint has been deleted. Deleted endpoints remain as audit tombstones and are not available for new operations. | Verify the endpoint identifier belongs to the authenticated tenant. If the endpoint was deleted, create a new endpoint. | info | No | 404 |
DALP-0527 | WEBHOOK_ | client | Webhook delivery not found. | No delivery record matches the combination of delivery identifier, endpoint identifier, and tenant, plus the event identifier on the receipt-create path. On that path, this also surfaces when the delivery's own counterSignedReceipts snapshot is false, meaning the feature was not enabled on the endpoint when that delivery was dispatched. | Confirm the delivery identifier and endpoint identifier are correct and belong to the authenticated tenant. List deliveries for the endpoint to retrieve valid identifiers. | info | No | 404 |
DALP-0529 | WEBHOOK_ | client | Webhook receipt not found. | No receipt record with that identifier exists in the current tenant scope. | Verify the receipt identifier belongs to the authenticated tenant. Use the receipt list endpoint to retrieve valid identifiers. | info | No | 404 |
DALP-0533 | METADATA_NOT_FOUND | client | Metadata not found. | No metadata document resolved for this hash from IPFS or the object-storage mirror within the resolution time limit. | Verify the metadata hash and retry after the metadata source has replicated. | info | No | 404 |
DALP-0534 | WEBHOOK_ | client | Webhook subscription pattern is not recognized. | The subscription pattern does not match any registered webhook event type or documented wildcard form, or it requests retracted events without a matching source subscription that can create the rows retractions are derived from. A test event also gets this answer when it names an event reserved for internal emitters. | Use an exact registered event name, a lifecycle wildcard (*.pending, *.provisional, *.final, *.retracted, .recalled), a prefix wildcard for a registered event family (token.transfer.), or *. Pair every retraction pattern with a pending, provisional, or final source subscription. | info | No | 400 |
DALP-0535 | WEBHOOK_ | client | Webhook endpoint URL must use HTTPS. | The endpoint URL uses a scheme other than HTTPS. Untrusted destinations must be HTTPS so delivery traffic is encrypted and the SSRF guard can apply its public-address policy. | Register an https:// URL, or ask an operator to add this exact origin to DALP_WEBHOOKS_TRUSTED_DESTINATIONS on a private-network install that needs plain HTTP. | info | No | 400 |
DALP-0536 | AUTHORIZATION_ | dependency | The permission check could not be completed. | The authentication provider could not evaluate whether the caller holds the permission this route requires, so the platform refused the request rather than admitting or denying it on a guess. | Retry the request. If the failure continues, ask your operator to confirm the authentication provider is reachable. | error | Yes | 503 |
DALP-0537 | WEBHOOK_ | client | Webhook Idempotency-Key reused. | The Idempotency-Key already started a registration from a different request, a registration that never completed, or one whose endpoint has since been deleted. | Send a new Idempotency-Key for a new registration, and reuse a key only to retry the identical request. | info | No | 409 |
DALP-0538 | WEBHOOK_ | domain | Webhook registration still in progress. | Another request with the same Idempotency-Key is still registering its endpoint. | Retry the identical request with the same Idempotency-Key after a few seconds. | info | Yes | 409 |
DALP-0539 | USER_ | domain | Cannot approve version while fields “ {value}” are missing or still need changes. | An approval must leave the version approved. A required field that is empty, a field a reviewer marked changes_requested, or a document an open action request still waits for keeps the version under review, so the approval is refused and writes nothing: no field verdict and no review outcome. | Wait for the investor to supply the listed fields or documents, or correct the fields with PATCH /api/. A reviewer who did not make the correction then approves the version. | info | No | 409 |
DALP-0540 | WEBHOOK_ | client | Webhook replay range ends before it begins. | The replay range's toBlock is before its fromBlock. | Send a toBlock at or after fromBlock, then retry. | info | No | 400 |
DALP-0541 | WEBHOOK_ | client | Webhook replay chain is not available for this organization. | The replay's chainId names a network the active organization has no network for. | Send the chainId of a network listed in the organization's settings, then retry. | info | No | 400 |
DALP-0542 | WEBHOOK_ | domain | Webhook endpoint changed since you read it. | Someone else saved a change to this endpoint after you read it, so your change was not applied. | Read the endpoint again and reapply your change to its current version. | info | No | 409 |
