gcloud crash while deploy app

[Amit Shakya]

I  have Nodejs app running on GCP I made few changes and update pull git branch code, It is running fine on port 8080 on gcp,  but after doing gcloud app deploy it throws me an error,

ERROR: gcloud crashed (TypeError): expected string or buffer , and there I found package-lock.json file, I read on docs it may be an issue, it can cause gcloud development failed, so that I delete package-lock.json but still not working

here my app.yaml

runtime:nodejs

env:flex

env:flex

This is correction I did which fix the issue

env: flex

just add little space.
