For reference later, the problem here is that Avro's `BuildAvroProjection` can fail if the expected schema and Avro schema don't match. The problem in `GetProjectedIds` caused an empty `data_file` field to not get projected in the result of `PruneColumns` because no ID was returned to select it. The number of fields in the final Avro projection must match so that all column indexes align between the expected Iceberg schema and the schema passed to the Avro resolver. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
