Unable to retrieve sections from OneNote - 40001 error code

I was trying to use the Create a OneNote page for new Google calendar events template. However, it fails at the step where it retrieves the sections within a notebook to populate the dropdown. I have also tried to create a task withGet Sections in Notebook step and I see a 400 - Bad Request response. The response details are below. Get Notebooks action works fine though.


I have just started using Power Automate. Can someone guide me with the setup? Is there some setting that needs to configured before I can start using the OneNote connector?


Response body


"error": {
"code": 400,
"message": "Error; unknown error code encountered when attempting to retrieve the site Id for the supplied notebook. Code: 40001",
"source": "",
"path": "choose[4]\\when[1]\\choose[2]\\when[1]"

How were you initiating the Flow? I had one of my users get the same error when the Flow was generated from a PowerApp. It happened when the user was opening the PowerApp within Teams and my suspicion is that they had not been logged through the SSO correctly and didn't have the right access. The error has not occurred for anyone using the Flow through the web link for PowerApps (which requires the SSO).
