I have an issue with a request participant. When I query the issue via REST API, I get an empty list back. I have documented the whole thing with screenshots. How is this possible? It's also good to know that I can't find the user via the search. If I create a JQL, for example, I can't find the user there either. The users that are found there are others, but not the one that was added to the issue as a request participant. I need the accountId of that account to do some other operations. How can I get it?
