When setting up Azure Static Web Apps and using Github workflow, sometimes pull-request builds will fail. The error is:
"This Static Web App already has the maximum number of staging environments".
Here's an excerpt from the Github Workflow build log:
How do I remove some of the staging environments so builds / pull-requests can complete?
The reason for this is most likely because you've opened PR and closed them before the build has completed. Doing so leaves them in a "void" state, and is a current limitation of Azure Static Web Apps. In order to complete the builds you need to delete some of the previous staging environments first. The free hosting plan has 3 staging environments, while the Standard has 10.
You do this by going to your Static Web App in Azure and clicking "Environments" (Marked 1). Your staging environments are displayed under "Staging".
Then check the ones you want to delete (Marked 2) and click "Delete" (Marked 3). That's it. Now you can re-run your pull-requests and the build will complete.
