Reset Origin of a StreamSets Pipeline using another pipeline

I want to reset the origin of a StreamSets pipeline, using another pipeline. I made a pipeline that sends 1 useless record to HTTP client component. The HTTP client contains the RESTFUL URL to reset the origin of a pipeline. It's something like that:

Resource URL: http://<hostname>:<port>/rest/v1/pipeline/StreamSetsPipelinec78f8739-8adb-47ad-beaa-77b3de60038d/resetOffset

HTTP method is POST

I tested it and it doesn't reset the origin.

Can anyone help me?

Solution

Have you tried using curl to test it first? For example, assuming you're targeting SDC (not SCH), something like this should work: curl -u admin:admin -X POST http://10.0.0.199:18630/rest/v1/pipeline/SDCHTTPClientd8bc16bc-4b4a-49cd-ba4c-41d7831ff5bd/resetOffset -H "X-Requested-By: SDC"
From HTTP Client, what do you have set for auth type and are you passing the right credentials?
Are you passing header attribute X-Requested-By?
In any case, are you getting any errors?
Note that this REST API endpoint does not return response body... just response code 200
