I also met this error at beginning, I do have a docker hosted mysql and created specific db for this test. until I restarted the webserver, I found out that it fetchs the DB info when you start the webserver. So seems it persists the info into vectordb for quick search. also means the db dialogue is not "realtime" querying the metadata info of your MySQL DB, once you do some changes on your db, you have to restart the webserver? how can I refresh the db info without restarting, wish can do it on GUI, thanks.
