Description

Iceberg tables can be identity partitioned by any type, e.g. int, date and even float.

If a table is partitioned, the file path contains the partition value in human readable form. When an UPDATE or DELETE command is executed, the delete file contains the file path to the referenced data file. It seems that DATE type is converted to this form incorrectly, and cannot be parsed by the Catalog and throws an error.
