Tracer error list

The response body is a structured error object with the following shape:

{
   "code":"<error_code>",
   "title":"<error_title>",
   "message":"<error_message>"
}

Field definitions

code: A unique, stable identifier for the error. It is a four-digit numeric string drawn from the shared platform error registry (for example, 0347).
title: A brief summary of the issue.
message: Detailed guidance for resolving the error.

Field-level validation Struct-level field validation failures return code 0009 with the title Validation Error and a message that names the specific field and constraint — for example, transactionType must be one of [CARD WIRE PIX CRYPTO]. Examples:

{
   "code":"0009",
   "title":"Validation Error",
   "message":"name is a required field"
}

{
   "code":"0341",
   "title":"Expression Type",
   "message":"Expression must return boolean."
}

Authentication failures do not use a numeric registry code. A missing or invalid API key returns HTTP 401 with "code": "Unauthenticated", "title": "Unauthorized", and "message": "API Key missing or invalid". Match on the literal Unauthenticated string. A Bearer token that parses but lacks the required sub claim returns HTTP 401 with "code": "0474".

General errors

Multi-tenant and authentication errors

The instance returns HTTP 503 with a Retry-After header when it reaches its per-pod tenant worker cap; clients should back off and retry. A Bearer token that parses but lacks the required sub claim is rejected with HTTP 401.

0474	Unauthorized	Bearer token is missing the required ‘sub’ claim; identity cannot be attributed.

Multi-tenant bootstrap errors

These codes surface only at service startup, when MULTI_TENANT_ENABLED=true and a required configuration is missing or incompatible. They appear in startup logs and prevent the service from starting; they never reach /v1/* API consumers.

`code`	`title`	`message`
0451	MTConfig Required	Multi-tenant config: cfg is required.
0452	MTLogger Required	Multi-tenant config: logger is required.

0458	MTAPIKey Only Validation Confl	MULTI_TENANT_ENABLED=true is incompatible with API_KEY_ENABLED_ONLY_VALIDATION=true.

Readiness probe errors

These codes are surfaced by the operational /readyz endpoint and by the worker-supervisor lifecycle. They appear in the error field of the /readyz JSON response — which carries the code only — not in /v1/* API responses. The title and message below describe each code for operator reference.

`code`	`title`	`message`
0436	Rule Cache Warm Up Failed	Rule cache warm-up failed.
0459	Readyz Pg Connection Not Established	Postgres readyz: connection not established.
