I am trying to follow the instructions of this video Duplicate a Power Automate Flow with Web API - YouTube
to duplicate one of my flows. The flow that I want to duplicate is called 'Approval' and it is used to automate the approval process of some documents.
Problem
When I use the Invoke HTTP request from Entra ID to call the following API:
- api/data/v9.2/workflows?$filter=name eq 'Approval'
I get an error message that says 'The resource could not be found'.

What I tried
I tried to turn the flow on and off again, but the error persisted. I also tried to rebuild the flow in a different environment, but I got the same error
Question
What could be the issue for this error and how can I resolve it? Is there something wrong with the API call or do I miss some setting to run this api call?
