not compatible with zappa for serverless deployments

cc: @miserlou

So I ran the app locally for the first tutorial example here: https://plot.ly/dash/getting-started

I tried deploying via zappa and got the following error:

(venv) rich@vbox:~/repos/explore_dash$ zappa deploy test                                                                                             
Calling deploy for stage test..
Creating zappa-permissions policy on ZappaLambdaExecution IAM Role.
Oh no! An error occurred! :(

During handling of the above exception, another exception occurred:

I removed the dash and dcc local files and it deployed fine. However, when I go to the AWS URL, I get the following error:

"{'message': 'An uncaught exception happened while servicing this request. You can investigate this with the `zappa tail` command.', 'traceback': ['Traceback (most recent call last):\\n', '  File \"/var/task/handler.py\", line 433, in handler\\n    response = Response.from_app(self.wsgi_app, environ)\\n', '  File \"/var/task/werkzeug/wrappers.py\", line 903, in from_app\\n    return cls(*_run_wsgi_app(app, environ, buffered))\\n', '  File \"/var/task/werkzeug/test.py\", line 884, in run_wsgi_app\\n    app_rv = app(environ, start_response)\\n', '  File \"/var/task/zappa/middleware.py\", line 66, in __call__\\n    response = self.application(environ, encode_response)\\n', \"TypeError: 'Dash' object is not callable\\n\"]}"

I get the following when tailing the logs:

[1498077793326] /var/task/plotly/tools.py:103: UserWarning:
[1498077793326] Looks like you don't have 'read-write' permission to your 'home' ('~') directory or to our '~/.plotly' directory. That means plotly's python api can't setup local configuration files. No problem though! You'll just have to sign-in using 'plotly.plotly.sign_in()'. For help with that: 'help(plotly.plotly.sign_in)'.
'Dash' object is not callable

If the dash and dcc files are necessary, is there a way I can rename them and reference them separately?

Also is there a way I can run the first tutorial in offline mode?

thanks!

Yes. Those would each be a separate stage on your zappa deployment. I threw up the POC here: https://github.com/mcrowson/zappa_dash

If you want to get more details check out the Zappa docs: https://github.com/Miserlou/Zappa
