Exact same issue, for english, when selecting from an area. Same output. Same system (albeit, Silverblue)

I too encountered this issue; Frog 1.5.1, GNOME 47 on Wayland, Arch.
In services/screenshot_service.py, at the beginning of decode_image I added:

# replace %xx escapes with their single-character equivalent 
if isinstance(file, str):
    from urllib.parse import urlparse, unquote
    file = unquote(urlparse(file).path)

...and with that the issue disappeared.

Apparently decode_image receives a path with '%xx escapes', and apparently Image.open fails to interpret these.

This was fixed in Frog 1.5.2, released 3 weeks ago. Make sure to update your apps!

This issue (and #98) should be closed @amka

I am using v1.5.2, and I am still getting the same error:

@xplosionmind Unfortunately, Frog is not correctly logging the error, and the warning above is unrelated. I am also unable to reproduce the issue on Fedora 41/GNOME/Wayland + Flatpak. Could you clone the repo, apply two simple changes, & then run it so we could get actual info on what's wrong?

1. Replace line 141 of frog/services/screenshot_service.py with logging.exception("ERROR") which will produce a stacktace
2. Add an import logging

I would recommend using GNOME Builder which will make editing & running very easy.

Sorry for the late reply, @DaPigGuy!

I followed the steps that you told me, and unfortunately I can’t reproduce the bug either… It works with all the three options to get an image to extract text from! Maybe the log could shine some light on the matter:
