Dash app OK in VS Code but does not work inside DSS

Pierre_BEJIAN

Hi,

Everything is in the title. I have a webapp which is OK outside DSS (VS Code and local Python installation).
The same script does not work inside DSS.
When I lauch the backend I have an animation with a "Please wait".
And after a couple of minutes I have this message :

#————————————————————— 
Oops: an unexpected error occurred

Webapp backend start timeout

Please see our options for getting help

HTTP code: 500, type: java.io.IOException
#————————————————————

Any ideas ?

Thanks and BR

Not every version of Dash may be supported and the way you run Dash apps outside Dataiku may be slightly different in DSS. So I suggest you start with a working Dataiku Dash Webapp and then slowly move your app to identify what is causing it to break:
