You could enable extension debug output by pasting the following command in Terminal:
defaults write com.pilotmoon.popclip EnableExtensionDebug -bool YES
then Quit and restart PopClip.
(note, substitute com.pilotmoon.popclip-setapp if using Setapp edition)
Then open Console app and set the following filters process: PopClip, category: Extension
Now set Console to “Start” & “Now” you should see the API calls going in and the responses. You can also add debug using print(), e.g. such as print("varname:", varname); in the code if that helps.
