I am getting this error when using the mysql for excel plugin.
Connection attemp failed The given key was not present in the dictionary.
The server is: MySQL 8.0.30 on Ubuntu I have installed MySQL connectors and workbench to 8.0.30 on the client side. The excel plugging is the latest of the archived version 1.3.8
The plugin will however work with other servers eg MariaDB version 10.3.34.
