Issue Summary

When attempting to create a Jira ticket from a pull request comment, the "Approvers" field does not work. In the Jira ticket creation dialog, it always shows "searching," and Bitbucket logs display an HTTP error code 400, while the browser console shows an HTTP error code 500.

Steps to Reproduce

• Integrate Bitbucket DC 9.5.1(or any version) with Jira cloud(direct link or via tunnel).
• Create PR in Bitbucket DC, and make a PR comment.
• Create a Jira issue from the PR comment.
• Search the username in the Approvers field.

Expected Results

A valid user should be returned while searching in Approvers fields.

Actual Results

• The atlassian-bitbucket.log will write the following warning
