Can you share some code and error messages with us?

Due to security reasons, I can't share the entire code,
but a function, I'm trying to load and process a table using the following code:

map_df = DeltaTable.forName(spark, schema_table).toDF()

The schema_table variable contains the schema and table name where the error occurs. I've confirmed that there's no typo in the schema or table name, so the issue doesn't seem to be related to that.

Thank you Witold

schema_table variable contains the schema and table

forName doesn't expect a schema, of course only a table path.

yeah I know that

At the first time, That codes didn't work.
Without doing something,  I just run again

then That forName worked.

It's so curious

Another thing you could check is how the underlying data looks like. Maybe the actual writer of the data, messed it up.
