Invalid argument sent to create_engine

[rodmur]

Hi, running Airflow 2.6.1 and I'm seeing this problem:

[2023-06-19, 09:42:16 UTC] {process_utils.py:189} INFO - TypeError: Invalid argument(s) 'encoding' sent to create_engine(), using configuration MySQLDialect_mysqldb/QueuePool/Engine. Please check that the keyword arguments are appropriate for this combination of components.

there is a traceback error which gets down to:

File "/var/airflow/.local/lib/python3.10/site-packages/airflow/utils/process_utils.py", line 170, in execute_in_subprocess execute_in_subprocess_with_kwargs(cmd, cwd=cwd) File "/var/airflow/.local/lib/python3.10/site-packages/airflow/utils/process_utils.py", line 193, in execute_in_subprocess_with_kwargs raise subprocess.CalledProcessError(exit_code, cmd)

Just wondering what the problem might be? I don't know why an incorrect parameter would be being passed. Is this due to a bug in Airflow? Or is it something the user may be doing?
