rfc9457: false
note: >-
  Accenta publishes no error reference on any public page, and the effiPilot API reference is behind
  the customer login, so this catalog is limited to error envelopes actually observed on the wire.
  Two distinct envelopes were returned by the platform, which indicates more than one service behind
  the same nginx front door. Responses are plain JSON, not application/problem+json, so the surface
  does not implement RFC 9457. Only observed entries are listed; the full error taxonomy is not
  public.
envelope:
  primary:
    fields:
    - message
    example: '{"message":"Route not found"}'
  secondary:
    fields:
    - message
    - error
    - statusCode
    example: '{"message":"Cannot GET /api/v3/api-docs","error":"Not Found","statusCode":404}'
  content_type: application/json; charset=utf-8
problems:
- status: 404
  message: Route not found
  envelope: primary
  meaning: >-
    The requested path is not a registered method on the effiPilot API for this request context.
    Returned both for genuinely unknown methods and for the /api/doc reference route when no
    authenticated session is present, so a 404 here does not distinguish "does not exist" from
    "not visible to you".
  observed_on:
  - GET https://app.accenta.ai/api/
  - GET https://app.accenta.ai/api/doc
  - GET https://app.accenta.ai/api/health
  - GET https://demo.accenta.ai/api/openapi.yaml
- status: 404
  message: Cannot GET <path>
  error: Not Found
  status_code_field: 404
  envelope: secondary
  meaning: >-
    Framework-level not-found from a second service behind the same host, echoing the HTTP method and
    path. Distinct from the primary envelope above.
  observed_on:
  - GET https://app.accenta.ai/api/v3/api-docs
- status: 403
  message: null
  envelope: html
  meaning: >-
    nginx returns an HTML 403 for the whole /.well-known/ prefix on the platform hosts — an
    infrastructure denial, not a JSON API error.
  observed_on:
  - GET https://app.accenta.ai/.well-known/security.txt
not_captured:
  authenticated_errors: true
  note: >-
    Validation, authorization and business-rule errors cannot be observed without customer
    credentials. Nothing here should be read as the complete effiPilot error taxonomy.
