fix: improve error message for unknown input item type in responses API (#15424)
发布于
2026-04-09 00:41:12 +00:00 The default branch in unmarshalResponsesInputItem had two issues:
- It referenced typeField.Type instead of itemType; these differ when the
shorthand role-based format promotes an empty type to "message", meaning
an unhandled type would show the wrong value in the error string. - It used %s formatting, so an empty type field produced the unhelpful
message "unknown input item type: " with no indication what was missing.
Fix by using itemType (the resolved value) with %q quoting, and add a
dedicated message when itemType is empty (both type and role absent):
"input item missing required 'type' field".Tests added for the empty-type and missing-type cases.
