Describe the Bug
I've recently installed Recognize and let it scan all of my photos (about 66,000 of them). Now I'm trying to go through and clean up detections. I went to the web app -> Photos, then selected "People" to view who it found.
Picked a face, gave them a name. Picked another face that was the same person, selected "Merge with a different person," picked their face out of the lineup. Instantly, a stream of messages "Failed to move [image filename] to person [person].
I turned on debug logging and tried it again. The message associated with the event, as far as I can tell, is:

I am slightly nervous that it is trying to actually move the file, but I assume that is not the case. Anyway - I'm not super familiar with this code but the message doesn't jump out as being particularly helpful. Hope it means something to somebody else!
Expected Behavior
I expect the detection groups to be merged into 1 person
To Reproduce
Attempt to merge two detected people as described above
