Firebase-config.json is not created!

I had multiple apps for my project, but now I have deleted all but one, but still it causes very big problems.

{
"status": "error",
"error": "Project fjolträsk has multiple apps, must specify an app id."
}

And since the config file did not exist before I have no idea how it should look.

Ok, tried to side step the problem by using another project. Now no config file is created and I still have the error in my Chrome consol:

App.jsx:31 Uncaught TypeError: Cannot read properties of undefined (reading 'sdkConfig')
