Why are my authorization provider variables getting overridden?

[Innoviox]

I am attempting to set up google authorization in a supabase preview branch. I copied over the client ID and client key variables that work perfectly fine in my production branch. However, now whenever I commit to the branch, they get reset to placeholders somehow, which then break the authentification flow since they have illegal characters:

How can I prevent this? What is even causing this?

This might be a bug in the latest CLI as it now handles copying the configs from your local to your remote project. I don't have the branching feature on any of my project so I'm unable to test this. I would suggest opening an issue on the https://github.com/supabase/cli repo about this.

Thanks for reporting this issue. We will fix it so that you can continue setting up external auth provider on preview branch via dashboard.

Meanwhile, if you have any [auth.external] blocks in config.toml, please comment them out or delete them so it won't be picked up by branching.

Is there any way to set this up so it works automatically? I don't want to have to manually add back in my client secret to every preview branch.
