I'm using Jira API token to hit all the zapi apis as mentioned in the link - https://support.smartbear.com/zephyr-squad-server/docs/api/how-to/create-tests.html
And, I'm using postman client. Any Jira is working properly, for e.g. https://xxxxx.atlassian.net/rest/api/latest/issue/TER-2
However, any request continaing zapi is throwing the error as below.
