Failed to download action while trying to run checkout step

No source file or test is identified. Start by reproducing the workflow and reviewing the runner logs around “Getting action download info” and the failed api.github.com request; done requires determining whether the checkout action or runner download path is responsible and documenting a verified resolution.

There's this weird error that I'm getting while running builds on my repo:
