Solution:
can you try below
Change logic in creation mode:
Only use .mode("append") or .mode("overwrite") when the table exists.
Use .mode("ignore") or .mode("errorIfExists") (default) appropriately.
Avoid .mode("overwrite" in streaming foreachBatch to prevent dropping the table schema and causing errors.
Create the table explicitly before streaming starts:
Manually create the Delta table once outside the streaming foreachBatch logic.
Inside foreachBatch, only append data or perform merges on the existing table.
Check and clean up checkpoint location if needed:
Sometimes checkpoints get corrupted, causing streaming retries to attempt table creation again.
