Reproduce the failure with a DynamicBucket Paimon table and an insert from a Hive table, using Paimon 0.5. Start by tracing the DynamicBucket path where GenericRow is rejected in favor of DynamicBucketRow. Done means the reported insert no longer fails for the reproduced record type, with a regression test if the relevant test location can be found.
