workspace_import_file_invalid
The CSV cannot be imported. reason: file_too_large (1 MB), too_many_rows (2,000), headers_invalid (first row must name email plus any of name, role, team, teams, skills, status, queue, queues), empty_file, not_utf8, csv_malformed. Row-level problems are not errors: the preview marks each row.
Problem shape
Every non-2xx response is an RFC 9457 application/problem+json body. The type URI below is stable and machine-matchable, so branch on the final path segment (the code) and treat the status as redundant confirmation. See the error-handling guide.
