Can't retrieve request transitions

[Carlos Llamacho]

I'm working at integrating a project with Service Desk when I will be creating requests and moving them along the transitions. I can create the issues correctly, but when I go to retrieve the available transitions for a specific issue I always get an empty list.

Authentication method: OAuth2.0
Url: https://api.atlassian.com/ex/jira/{workspace_id}/rest/servicedeskapi/request/{issue_id}/transition
Response: {"size":0,"start":0,"limit":50,"isLastPage":true,"_links":{"self":"{url_i_sent}","base":"https://panoptadev.atlassian.net","context":""},"values":[]}

I can get the request details via `/rest/servicedeskapi/request/{issue_id}}` and can track the status change as they are being done via the web interface.

I also tried with several workflows and always get the same result. Putting a non existant issue id returns a 404 as expected, and I get a 403 if my token are expired as expected.

If anyone has any idea why this happen I would be really grateful.
