Following the steps here worked for me. It looks like this request may have failed for @lanitochka17, I'm gonna see if I can find logs

Looking at the logs we get 406 Chat report with these participants already exists with different ID

Hence I believe this is the same instance of #22663 where the issue is stemming from the fact the other user is not knownUser and hence we dont retrieve the login field for them, which is needed to find the correct chat/ or pass the correct email to the command.

I dont think this should be a deploy blocker but its something we have to resolve after the secure login migration as there is no clear plan ahead afaik. Alex B is ooo today and Puneet is out for a week so we should probs discuss tomorrow

I missed this, but now I'm able to reproduce, and I think I found a relevant error in the logs

Throwing exception with message: '406 Chat report with these participants already exists with different ID' from auth/lib/Transaction.cpp:1638
Error processing command 'CreateIOUTransaction' (406 Chat report with these participants already exists with different ID), ignoring.

I reproduced the error in production (logs), so I don't think we need to block on this, since it also fails, even though it looks a little different
