When setting up automatic GitHub-triggered deployment as per these instructions on the AWS blog I ran into a problem that's been very difficult to diagnose. When I push to my GitHub repo the GitHub Auto-Deployment service runs fine, but AWS CodeDeploy service fails with seemingly no information other than this bit of text when I hover over the error icon: "Last delivery was not successful. An exception occurred."
I've been trying to find a way to get any logs from GitHub's failed service run to get any kind of information about what kind of exception it actually ran into, but unless I'm blind there seems to be nothing. The setup as far as I can see is identical to the AWS blog post. Deploying manually through CodeDeploy using the GitHub repo works perfectly fine.
I'm wondering if anyone else has run into this when setting this up and figured out what happened (or can point me in the right direction)?
