Attachments are not getting attached in jira after getting status code as 200

While trying to hit add attachment api service from salesforce, its returning status code as 200 with no response body.

I am using basic authentication in order to hit the service.

Please let me know what’s going wrong here.

hello salesforce. could you indicate what endpoint in the API docs you’re hitting and show us an example of the request through something like postman? You should be sure to redact sensitive information such as your basic auth header and/or the URL for the site you’re hitting.
