Unable to assign issue using JIRA Rest API Python

[Ankit Bansal]

jira.assign_issue(key, assignee)

Seems to be failing with the following error

User 'JIRAUSER<id>' does not exist

Although, navigating to https://<jira_host>/rest/api/2/user?username=<username> 
has the correct user id "JIRAUSER<id>"

Other methods like creating an issue, transitioning the issue, etc. all work fine.

Python package version: jira==3.0.1

Turns out this was a bug in the jira Python library  (v3.0.1)

Good to know. Thank you @Ankit Bansal for letting everyone know.

HI @Ankit Bansal ,

Just to be sure.. Is that specific user having assign permission?

[Ankit Bansal]

Hi @Mirek ,

Yes the user has the assign permission, I am able to assign the issue to the user through the JIRA UI, just not through the jira python client which invokes the Rest API. Also, this is not for one specific user, but multiple users.
