internal_error

What it means

Ironfang Finance failed in a way that is not the caller's doing. On an operation that processes a document the outcome is indeterminate and no usage was charged; on a read it says nothing about any document.

What to do

Retry. If it persists, contact support with the request_id.

outcome

Indeterminate, with usage_charged false, when the operation was processing a document; absent on a read.

Problems follow RFC 9457 and are served as application/problem+json. A validation finding is never a Problem: an invalid invoice is a successful response that lists its findings. See every problem type, the Finance guide and the OpenAPI contract.
