Jira xray rest api request

Yuri-Test

Hi. I try to launch rest api against xray in jira, I have made authorization Token from client_id and client_secret. I pass with request header
with Bearer:TOKEN https://kanghealthio.atlassian.net/rest/raven/latest/api/test/KE-10566/step
But answer is:
{"message":"null for uri: https://kanghealthio.atlassian.net/rest/raven/latest/api/test/KE-10566/step","status-code":404}
Tell me please what I do wrong? Thanks in advance!
