HTTP Method Patch is not Supported error while trying to update Task Instance of SCP Workflow

Utkarsh — Sat, 03 Feb 2024 22:08:29 GMT

Hi Experts,

We are implementing an SCP workflow and we have a requirement to complete the User Task from an action taken from a custom Fiori App. But, when we are testing the Patch method for Task Instance API in Postman, we are facing an error saying 'HTTP method Patch is not supported'.

We are facing the same error even from SAP API Hub for Sandbox environment.

Any inputs will be highly appreciated.

Please check whether it works if you use PATCH instead of Patch. HTTP verbs are case-sensitive.

Can you tell us the path, you're using ?

No tobias.breyer, we don't write the method name anywhere, we just select it from the dropdown in Postman.
