Hi @dadrake3 

You are encountering this error only when you run against the Unity Catalog. In Unity Catalog, Table Access Control is enabled by default. You must grant SELECT permission on files so the selected user(Who is running the DLT pipeline) can access them.

You can follow the below KB link,

Please leave a like if it is helpful. Follow-ups are appreciated.

Kudos,
