Module loading error after changes
After any changes inside my custom modules solara crashes when attemptin to reload them, if i stop the app and restart it runs without a problem. Changes just as simple as a new space will break the hot reloading capabilites. The call stack is showing there is an issue with the a key (module name) in the autorouting package. I also noticed that as im working with the app running it periodically reloads and crashes in the same manner.

Thanks you for letting us know.
Can you share the error?
Not a problem here is the callstack I am getting:
(venv) PS C:\Program\Process> solara run solara_main.py

KeyError: 'app.models'
hmm, where is the app directory? (i.e. what is the absolute path of app/init.py) ?
Here is what my Root looks like:
Process/solara_main.py
Process/app/models/basemodel.py
Process/app/init.py
Process/models/init.py
Process/app/helpers/init.py
Process/app/helpers/helpers.py
I can kind of reproduce this when I don't add a
__init__.py in app/models, then I get a keyerror for 'app'
could you try adding an __init__.py file in that directory, otherwise it's a namespace package, and it seems that either python acts weird with that, or solara should remove some caches in python to fix this.
Either way, would be nice to get a confirmation is this workaround works for you.Let me give it a try a little later today and get back to you, thanks for the assistance!
This appears to have solved the initial refresh problem, that being said i've encountered and other issue which I will investigate. Thanks for the assistance
