Why can't I get groups of user jira? Using rest api

[Kudimov Mikhail]

Hi! 

I want to get enumerate the groups of Jira user using GetUser

But I get this response. 

Why the list of groups is empty?

Thank you in advance!

I solved my problem.

I need an extra query parameter:

"expand": "groups,applicationRoles"

Can you share your commands?

This worked for me to get the groups :

/rest/api/2/user?username=username&expand=groups

[Deleted user]
