I'm trying to configure an AWS Greengrass group through their JavaScript SDK, and I get everything up and running up to where I have a deployment. The issue is that the deployment seems to be stuck on "in progress" and there are no cloudwatch logs to help me.
I looked at the core device, and this is what I saw in the /greengrass/ggc/var/logs/system/runtime.log file:

I've checked and I'm able to successfully hit the ATS endpoint using OpenSSL and the certificates that I have. I'm using Amazon's recommended certificate from the Greengrass tutorial RSA 2048 bit key: Amazon Root CA 1.
What are some diagnostic steps or clues where to go from here?
I've had this issue before. I believe it's just a bug with the internals getting mangled from a bad deployment.
The way I brute force hanging deployments are to create a new core and then add known working lamdbas in a working group to the new core, kill and restart the deamon on the core device, and then redeploy.
