To Reproduce

Update the Docker image and run n8n cointainer.

Expected behavior

When Watchtower received the latest update, it couldn't run the migration script for MySQL.

I expect n8n to start up.

Watchtower updates on 1c4dc7c3eb8a

Hey @mbakgun,

We have created an internal ticket to look into this which we will be tracking as "N8N-7992"

@mbakgun can you please share which version of MySQL you use?

And also, when the update came yesterday, I encountered error 1.72.1 (on the latest); before that, version 1.71.2 was installed and was running well.
