"FileNotFoundError: [Errno 2] No such file or directory" After Changing/Saving Settings and then a Reboot

My apologies if I'm doing this wrong or if this is a duplicate, it's my first bug report.
After changing camera settings in the UI and saving them, app.py fails to run.
I suspect that app.py can't find the config json file that's created when the camera settings are saved.

Steps to reproduce the behavior:

  1. Install picamera2-WebUI and all prerequisites
  2. Execute app.py - works fine
  3. Use UI to change and save camera settings
  4. Stop app.py (or reboot the whole machine)
  5. Execute app.py - fail (see below dump)
    Steps I've used to "fix" it:
  6. Edit camera-last-config.json and change Has_Config to false
  7. Execute app.py - works, but settings are reverted to defaults (as you'd expect when telling it to ignore the config file)

Here's a dump of the output:

I'm using a Raspberry Pi 4 with 4 GB of RAM and I'm running Raspberry Pi OS Lite 64 bit.

monkeymademe commented

I don't know if its the config but maybe something else going on. I need to know what camera you are using (v3 or arducam?)

Also try updating the Pi like this:

sudo apt update
sudo apt full-upgrade

Lets see if that helps

monkeymademe commented

Acutally can you tell me what files are in the static/camera_config folder and also paste in whats inside the file camera-last-config.json

monkeymademe commented

Ok I tried to make the saving loading and using default config a little more robust so if a file is missing the default settings will be taken and the missing file is off the record

I hope this will solve the issue. If not please reopen the ticket
