Action failed but it was marked as successful

While deploying, I had this error (appspec.yml does exist though) and the action was marked as successful.

If you need more code let me know. Deploy is running on a self-hosted Amazon Linux 2 VM

For future reference about the missing appspec: this

I was being frupid and didn't add the actions/checkout@v2 action

The build being marked as successful issue remains

Edited due to missing info + closed issue by mistake
