Hi, can you show the full error message from the dev tools console? Also, are you testing using a saved game or new game?
Edit: I believe I see the issue, are you by any chance using a saved game that had pictures showing already at the time of save prior to adding this plugin? I am able to reproduce the issue in that case. I can release an update to handle this case, but in the mean time you might want to start a new game, add a temporary event to clear and re-show any existing pictures, or run the following js in an event script call:
for(const pic of $gameScreen._pictures) {
pic?.CGMZ_clearClickablePicture();
}
The issue is most likely that you have pictures that exist in your save that do not have clickable picture data.
