Intermittent disconnection - Use with edge device

[Minipada]

Hi, I am trying to use the cognito plugin on robots in a place where internet connection is not stable.

In this case, the whole api won't load because auth is not loading properly. Click to expand the error.

I am confused on how I can handle it. You can reproduce it locally by cutting of the internet and trying to reload.

Having a try/except in the plugin, handle the timeout and return an error would be the solution. I'm trying to do it myself but doesn't seem so straightforward to me. Any idea how to proceed?

Thanks!
