Different between key and username in Jira

[Winni_Chang]

Hi,

I encounter a problem that my program cannot find the user key.

        text: User 'JIRAUSERXXXXX' does not exist.

But actually this user does exist and was already added in our project space. (Of course, my agent account is Admin.)

And I can use this user's username to do some actions but the key is invalid. I have processed a lot of other users in our project space, but they do not have the same problem.

I found that almost key is the lower case of username, but this user's key is JIRAUSERXXXXX.

Therefore, I would like to know the difference between username and key in Jira.

Thank you.

Regards,

Winni

See this post.
Apparently this is because of username renaming.
Can't find the link with cwd_user though.
In which table is this stored?

Hi,

Is this caused by API or?

Thank you.
