What happened?
Hi !! 
You can see this video : Awesome Screenshot
When I do a “match”, often I’ve got a Error message as you can see on the video, but the match is still applied to the encounter.
The account I use is in edit collaboration with the owner of the 2 encounters I’m matching :
What did you expect to happen?
The same but without the error message.
What are some steps we could take to reproduce the issue?
Here is the match results : https://www.whiskerbook.org/iaResults.jsp?taskId=4afa34c6-2124-4b62-8b61-b21c7f57e7f8
You can go to the encounter, remove the “identity” CHACOR, go to match results again and try to match the picture to a CHACOR picture.
