Jira put request for assigning a user to an issue not working

[Will Denton]

For some reason I am unable to change the assigned user of a task through the rest API. I am currently building a python bot which should adjust the assignees but I am unable to do so.

Currently I am posting to this url with the proper headers and auth: 

"https://[mydomainhere]/rest/api/2/issue/TEST-2"

I am sending this json: 

{"fields": {"assignee": {"accountId":"****************"}}}

Does anyone know how to properly do this? all info I am finding on this problem is outdated.

@Will Denton What message from Jira do you get when you run your script?
