write_dataframe() does not finish

I'm trying to write a `pandas.DataFrame` into a table using the `write_dataframe `function but I tried waiting 10 minutes, and it does not finish.

I limited the size of the dataframe to have around 70 rows and 40 columns, the problem persists.

In the debugger, the code is stuck when calling the libray code `self.executemany(sql, arrays)` into `write_dataframe `.

How can I know what is the problem? I can read successfully another table. The table where I want to write was just created for testing purpouses.

Thanks
