Appengine deploy failing

I cloned the repo and tried to deploy this app in appengine - gcloud app deploy app.yaml, but it failed for because rimraf not found, so I had to move all devDependencies in dependencies and then rerun the deploy and now I get following error and no clue how to resolve -

Updating service [default]...failed.
