Are you sure that you right click on the photo (in the photo panel) and not the item? (Consolidating items does not prompt you for the new location, because you can have more than one photo in an item – I know that this can be confusing!)
According to the error in the log (file not found) Tropy should really prompt you for the photo. Looking at the path this looks like an old Apple Photos library – have you recently updated your Mac to Catalina? In that case it the photo’s are probably missing because of the update – unfortunately the best way to solve this currently is to use the script we wrote to update the paths (the files are difficult to find otherwise, because Apple renamed the originals).
