Data transforms - Copy data logs - Data load KUP-04026: field too long for datatype

Summary:

Using Autonomous database 26ai Lakehouse Data Transforms - Data Load (ODT) to ingest Fusion BI Cloud Connector (BICC) files.

For multiple BICC PVOs with large columns we experience KUP-04026: field too long for datatype. The tables created in the target schema are correctly typed and sized as expected however in the data load intermediary step the logs show Data Load uses CHAR (255) on all columns when dealing with .csv load log.

Is there a a way to instruct Data Load to use larger default char size when dealing with logs?
