Hi,

Any help is much appreciated.

Issue - I have a sharepoint list that has an 'assigned to' column. When I assign a list item to a specific user, I want to to create that user a task in Planner.

I have created and followed the steps here - https://www.sharepointsiren.com/2021/05/power-automate-sharepoint-get-column-changes/

This is the input uri -

_api/web/lists/GetByTitle('SPF RAID')/items/(75)/versions(3.0)"

This is my flow:

This is the error report:

Many thanks!!!

Hi @ Portfolio_Director

There is a mistake in API request, see below

API you have used

_api/web/lists/GetByTitle('SPF RAID')/items/(75)/versions(3.0)

But there is no need of forward slash after items, so correct format of url to be followed is

_api/web/lists/GetByTitle('SPF RAID')/items(75)/versions(3.0)

In the blog also, they have followed simmilar api uri which i have shared :)

Thanks & Regards,

I removed the forward slash:

_api/web/lists/GetByTitle('SPF RAID')/items(75)/versions(3.0)

But I still got an error message about the input string being wrong.

I did some more digging and found this article which helped solve the issue

Yes the forward slash was incorrect.

But I had to use the following code in the function. It did not like me using the ID and SinceVersionID in dynamic content. I think it was due to an error in the New Viewer in powerautomate. The old design view seems to be less buggy!
Items(@{triggerOutputs()?['body/ID']})/Versions(@{outputs('Get_changes_for_an_item_or_a_file_(properties_only)')?['body/SinceVersionId']})
