Dash app not loading #290

Open ad15665 opened 3 years ago

ad15665 commented 3 years ago

Hi, my application worked perfectly and then I tried to deploy my app onto azure. When I was going through the process of deploying, I chose to update all of my python packages (disaster). All other aspects of my app work fine except for the dashboard. When I click onto the page, I get a "Loading..." displayed in the top left-hand corner and then the page goes blank. I have no errors within my terminal. The only error I can find is after clicking "Inspect" on Chrome:

Any direction on how to diagnose would be really helpful. Thank you!

i have the same problem, i have done a lot but still there is no solution for this issue. I hope there will be an answer to this issue.

@ad15665 @muhamrii this sounds like package (or python) version incompatibility. Are the packages the same versions for the local and cloud environments? What versions of python are being used?

ad15665 commented 3 years ago

Hi @GibbsConsulting, I haven't actually got the cloud version up and running yet. In my local environment, I'm using Python 3.8.2 within pycharm on a macbook pro 2018... Thanks for helping!

Hi, try this: In settings.py, goto INSTALLED_APPS list,

comment out the "channels" and only use "channels_redis"

ad15665 commented 3 years ago

Hi, okay thank you, will try now.

ad15665 commented 3 years ago

Yes that worked!!!!!!!!!!!!!!!! Thank you thank you. How did you know to do that?

pgchj commented 3 years ago

Yes that worked!!!!!!!!!!!!!!!! Thank you thank you. How did you know to do that?

i guess the development server cannot handle the asynchronous connection well, so just removing the channel implementation...

GibbsConsulting commented 3 years ago

@pgchj @ad15665 @muhamrii v1.5.0 is now available. This should resolve the problem by using a version of channels < 3.0
