App Engine Flexable: ImportError: No module named PLACEHOLDER

[Andrew Wilson]

Here is the raw stack trace:

Traceback (most recent call last):
  File "/home/vmagent/python_vm_runtime/google/appengine/ext/vmruntime/meta_app.py", line 550, in GetUserAppAndServe
    app, mod_file = self.GetUserApp(script)

ImportError: No module named PLACEHOLDER

After a recent deploy to AppEngine flexable i get this spammed in the server logs. 

I have a very simple app.yaml - 

runtime: python27
vm: true
threadsafe: true
entrypoint: gunicorn -b :$PORT main:app

I have no idea why this is coming up or even how to start debugging. Any help would be greatly appriciated. Thank you

Hey Andrew,

Is this still occurring for you? If so, could you let me know the project ID via a direct email to me at pay...@google.com? I'd be happy to try to take a look into this.

Cheers,
