Hi guys,
I found a similar error in the below topic (although it is about DAQ), I have tried the suggested fix of eager_loading=True but I still see the error.
[SOLVED] Intermittent Dash Dependency Exception: "dash_daq" is registered but the path requested is not valid
Dash Python
I’m coming across an intermittent exception that I can’t quite figure out. I only see the exception when running the app through a WSGI like Waitress or Gunicorn. I do not see this error when running the app directly in developer mode.
I occasionally get the following exception error when loading the page. It’s not consistent, but it appears to prevent components from fully loading. I’ll see several charts with only a loading animation. If I refresh the page, the components usually update fine.…
I wondered if anyone might know what this error means in practise and what could be causing it?
Hello
@Pippo
,
If everything is working when you are testing, then I think you may be running into requests while the server is spinning up and is in an incomplete state.
I notice errors like this locally when I am using a flask server and hot reload. When I refresh too soon on the page I am adjusting, it will come up like this. For me, the page doesnt load quite right.
Since you are using render, if you are using a version that only spins up when it is requested, this could very well be the issue that you are running into as well.
Hi and thanks for the reply. I’m on the paid Render which I believe is permanently on, and I’m seeing the errors a long time after deploying or loading the server, so I don’t think it is to do with spinning up. It seems to occur seemingly randomly (I’ve seen it in the logs around the time of different user agents using the site) in the middle of what looks like normal operations of the site
