DIA-52910
Iceberg metadata validation failed for string
Cause
A metadata-derived Iceberg value is malformed, exceeds a supported bound, overflows a validated aggregate, or resolves to an untrusted object location while processing the named field.
Action
Correct or regenerate the Iceberg metadata so the named field contains a valid value, then retry the statement. If the metadata is expected to be valid, report this as a bug.
