Weird Jira servicedesk return 405 on getting the request attachment object

[Ian Russel Adem]

Hello There, following the docs here https://developer.atlassian.com/cloud/jira/service-desk/rest/#api-rest-servicedeskapi-request-issueIdOrKey-attachment-get, I need to get attachments(not download) for a specific request, but I got 405 which means according to http status code is method not allowed, with no other helpful message. I followed what your docs says but still no luck. Any ideas?

Kindly see attached screenshot.

Thanks,

Ian
