Hi all,
after upgrade to 25.04.0 my apps are not showing up (but are still running)
with the error code: I guess my custom logos are bugging the system…

Validation Error

so there are two questions:

  1. is there a short-term fix (like editigng the yaml directly and removing the icon) → where do I find the correct yaml?
  2. how to fix this longterm?

thanks!

Perhaps if you documented how you added the icons, someone might know what to do to reverse.

There is discussion of this being a feature in a future release. If you can’t find a “feature request”, please create one.

Edit: Its here: Allow custom icons for custom apps

thanks! for the long term solution info!

I figured out a short-term solution:
1.find the metadata.yaml file in .ix-apps
2. comment or remove the line with the corresponding icon: /… img_custom.png

in my case this was a custom app, and i had to commetn the icon: … lines in the main metadata.yaml and the one in the apps subfolder

thanks!
