Branch deploys not working

I have a repository which has the following branches representing checkpoints of the assignment: 1, 2, 3. I have now enabled branch deploys on all of these branches, but they aren’t getting deployed.

You need to successfully deploy each branch after enabling this feature. To deploy a branch, make a change to it and push it to the repository. You could push empty commits if you do not wish to change anything.
