Hi @brickster, How are you doing today?

Try dropping any existing table or metadata related to test_transact before creating it to avoid conflicts. Consider using a different table name or creating it in a new schema to bypass potential metadata issues. Explicitly define the schema in your DataFrame to prevent type inference problems. Restart your cluster to clear any cached sessions or metadata causing the error. Lastly, check for DBR version compatibility with Delta Lake, and consider trying a different DBR version if the issue persists.

Give a try.

Regards,
