Self-Hosted Jira Portal - Jira Query issue

We have Jira source which is a self-hosted URL. I am using Jira query component to fetch the data. Provided URL, User & Password. I can see objects as well as column names, however when I try to see sample or read data it gives below error:-

Invalid JSON markup. Expected json, but could not parse the response.

 

Matillion support team debugged it and found that self-hosted URL is going for OKTA verification. Do someone have any idea how can we resolve this issue?
