Errors

All errors come back as JSON with a consistent envelope. Status codes follow normal HTTP conventions; the body always carries a human-readable message.

Envelope

{
  "error": {
    "message": "Owner role required"
  }
}

Validation errors include an issues field with the flattened output from Zod, so you can map each issue back to the field that caused it:

{
  "error": {
    "message": "Validation failed",
    "issues": {
      "fieldErrors": {
        "name": ["String must contain at least 1 character(s)"]
      }
    }
  }
}

Status codes

• 400 — invalid body, invalid path parameter, or assume-role failure.
• 401 — missing or invalid Authorization header.
• 403 — authenticated, but the caller doesn't have the required role.
• 404 — resource not found, or the caller is not a member of the org they're targeting.
• 410 — invite has expired.
• 500 — unexpected server error. We log these; report persistent occurrences.

CORS preflight

Browser clients see CORS responses for cross-origin requests. The allow-list lives in the API stack; if your origin isn't in it the preflight will fail before your request body is ever inspected.
