Has anybody else gotten the ValueError: View function did not return a response?

app.py seems to run fine, but I get the stack trace page when I click on the Preview Workspace (the eyeball)

Is this Flask? I think you may be getting this error if your function isnt returning something. In Flask even if you return None you will probably get this error. Try return 'OK' and see if this fixes the error
