[BUG]: When creating custom login on onboarding-setup page I get the error "System setup has already been completed - you cannot do this again."

[sfstw]

How are you running VectorAdmin?

Docker (local)

What happened?

I have used your fantastic tool before and it used to work. This is why it's even more frustrating.

When I use some random email and "password" as password to create a custom login I get this error message

Error creating login: [000] System setup has already been completed - you cannot do this again.

Are there known steps to reproduce?

This is my .env file:

JWT_SECRET="some-random-string"
INNGEST_SIGNING_KEY="some-random-string"
DATABASE_CONNECTION_STRING="postgresql://vectoradmin:password@host.docker.internal:5433/vdbms"

I run docker-compose up -d --build vector-admin and when its finished I open http://localhost:3001/ and I get redirected to http://localhost:3001/onboarding-setup.

The UI is new and it says "Create your custom login". When I use some random email and "password" as password to create a custom login I get this error message

Error creating login: [000] System setup has already been completed - you cannot do this again.

I tried deleting the container and the images, pulling everything new and spinning them up again. Nothing helped. I'm stuck.
