Migration MySQL error on start: Error 1061 (42000): Duplicate key name 'idx_services_domain'

Describe the problem

In tonights update (I have automatic updates enabled via watchtower in composer) the netbird-server breaks because of this:

I had to delete the key manually now and restart so that it works and doesn't hang in a boot loop.
I have to turn off automatic updates now, because I can't trust the updates before personally checking them...

To Reproduce

Steps to reproduce the behavior:

1. Have version 0.66.2 installed
2. Automatic update with restart at night
3. ERROR

Expected behavior

The netbird-server container should start already

Are you using NetBird Cloud?

No, self-hosted

NetBird version

0.66.2

Is any other VPN software installed?

No

Debug output

Is shown above

Screenshots

Additional context

Have you tried these troubleshooting steps?

[ressys1978]

I too can confirm this issue with v0.66.2.

Rolling back to v0.66.1 allows the Management service to work.

When creating an Index, there should be a process that checks to see if one with the same name already exists first, check to see if the index is the same, delete and recreate it if necessary, or skip creating if it is not needed.

Can also confirm problem this exists.

In my case, I was updating to 0.66.3 and that failed. Have manually rolled back to 0.66.2
