[revmischa]

It runs okay if I deploy it without enterprise

[logandk]

I haven't tried Serverless Enterprise. Is there a way to test and replicate this for free?

[revmischa]

it's free to try. just run serverless login

[brett-matthews]

Im not sure if this is related, but when i execute;

sls wsgi serve

All good..

But when I deploy it I see this in CloudWatch;

    "errorMessage": "Error: Cannot find module 'wsgi_handler'\nRequire stack:\n- /var/runtime/UserFunction.js\n- /var/runtime/index.js",

@brett-matthews we're seeing that behavior too

Im not sure if this is related, but when i execute;

sls wsgi serve

[logandk]

I'm hoping to look into this very soon, will give it a try on Enterprise

[mikealche]

I'm also getting this just trying to run the Flask HTTP API example with the serverless offline plugin

[logandk]

@mikealche Run sls wsgi install before sls offline

[HumbertoSilv]

@mikealcheCorra sls wsgi installantessls offline

This worked perfectly for me, however I didn't understand the difference between 'sls wsgi install' and 'serverless-wsgi' and couldn't find anything by searching.
