FMEFlowLogFileRetriever no longer exists in FME 2025. How to use HTTPCaller to access Flow Rest API?

My long time transformer friend FMEFlowLogFileRetriever is not avaliable in FME 2025. The error asked me to use HTTPCaller to retrieve the job log file. So I used this rest point in the HTTPCaller’s Request URL with GET - https://my-fme-flow-hostname/fmerest/v3/transformations/jobs/@Value(jobid)/log. I tried the Basic and Web Connection authentications, but both gives the error “HTTPCaller (HTTPFactory): An error occurred while accessing the URL 'https://my-fme-flow-hostname/fmerest/v3/transformations/jobs/98/log'”. I have no problem publishing using the same Web Connection for the authentication, so don’t understand what the issue is. The jobid = 98 was run successfully on the FME Flow.
