Pulumi action tries to login to pulumi cloud even though we're using S3 backend

[Anne Stein]

What happened?

The pulumi action version 5.1.0 tries to login to pulumi cloud backend instead of the configured S3 backend. It is working fine with version 5.0.0.

Example

Run pulumi/actions@v5

    command: preview

Output of pulumi about

Does not apply since pulumi-action is used and pulumi about is not available in action.

the configured S3 backend.

What configured S3 backend? The config shown doesn't list backend.

[Fraser Waters]

I think you need to set the 'cloud-url' config option. Not sure how this was ever working before.

[Anne Stein]

We don't pass the cloud-url since it's defined in the Pulumi.yaml

backend:
  url: s3://<XXX>

[Luciano Fantone]

We are facing the same issue even with the cloud-url property correctly set. We end up downgrading to v5 which works just fine.

[Fraser Waters]

We don't pass the cloud-url since it's defined in the Pulumi.yaml

Ah... yes that's a regression.

We are facing the same issue

I think that might be a different issue. The old code ignored any error from login so this would have been silently failing. Although again not clear how this was working before if login was failing.

[Luciano Fantone]

What do you mean with login failing? The preview or update commands where executing fine and the state in the cloud was updated properly. Maybe I'm missing something else?

I know this new implementation show the error, but is there any way to check this login issues within the v5.0.0 action?

[Fraser Waters]

What do you mean with login failing?

As in pulumi login failing. Oddly the login flow for that and preview are the same as far as I can see so I'm not sure how this is in a state where login fails but preview was working.

I don't think the old action recorded these failures in any way. Doesn't even look like debug mode logs anything for exec calls. We'll get a fix out so this doesn't hard error.

I just released v5.1.1 of the GitHub action, which should solve this.
