Cannot deploy my app to App Engine after Installing Parse Dashboard

I followed all the steps to get the dashboard up and running, it works.

However, its created a problem for me. gloud preview app deploy gives me errors. It fails to deploy.

I installed the dashboard files within the same folder where I have my parse server.
Parse Server Directory: dev/appName-server/"server files, cloud code, app.yaml e.t.c
Dashboard Directory: dev/appname-server/parse-dashboard

When I run my command to deploy my server code gcloud preview app deploy I get this problem

Beginning deployment...

ERROR: (gcloud.preview.app.deploy) There is a Dockerfile in the current directory, and the runtime field in /Users/myUserName/Documents/dev/appName-server/app.yaml is currently set to [runtime: nodejs].

To continue using the [nodejs] runtime, please omit the Dockerfile from this directory.

Even After removing the DockerFile in my dev/appName-server/ directory, my deployment gets stuck at

Update: I deleted the parse dashboard from my server folder and reinstalled outside of it and the error still persists stopping me from deploying. gloud preview app deploy works when I delete the parse dashboard

This was likely a transient issue with App Engine. We've completely changed the way these deployments happen. Please let us know if this is still an issue!
