Invalid allowlist

What it means

The request was malformed, or a field failed validation.

Example detail messages returned with this error:

• allowlisted_license_ids must be an array of SPDX id strings.
• SPDX id too long (max 128): {id.slice(0, 40)}…
• Invalid SPDX id: “{id}”.

What to do

Correct the allowlist value - detail names what was wrong.

Response shape

All fremforge API errors are RFC 9457 problem+json:

{
  "type": "https://docs.frem.sh/reference/api/errors/invalid-allowlist",
  "title": "Bad Request",
  "status": 400,
  "detail": "..."
}

Branch on type, not on title or detail - those are human-readable and may be reworded.
