On prem Sentry jira integration for custom fields


We are having an issue with Sentry on prem and jira integration for custom fields. The jira template has been setup for two fields - code reviewer and tester. Both are custom fields and are user fields. When I type in those fields, it can prompt a user list and I can pick user from the list.

After integrating jira with sentry, the jira ticket in sentry shows code reviewer and tester as dropdowns instead of textboxes. When I type a user’s name in the textboxes, it spins, but returns a 400 error. When I inspect the browser console the below returns a 400 error.


Any idea how to integrate a custom field in jira for a user list with sentry on prem? We have Sentry 20.10.1 installed on prem
