Although there may be other ways to do this, it can be done using a HTTP request to SharePoint:

Uri: _api/web/lists/GetByTitle('People')/items(69) Headers: { "IF-MATCH": "*", "X-HTTP-Method": "MERGE", "Content-Type": "application/json;odata=verbose", "Accept": "application/json;odata=verbose" } Body: {'__metadata':{'type':'SP.Data.PeopleListItem'}, 'PMStringId':'', 'PMId':-1 }

Here is an example of clearing the PM field from a SharePoint List called People. The list item ID is 69:

Use the internal name for the Person field, not the display name.

To do the clear operation, you must know the correct ListItemEntityTypeFullName property of the list and pass that as the value of type in the Send an HTTP request to SharePoint body.

It seems that the ListItemEntityTypeFullName property value SP.Data.BTToolsDataListItem specified in the flow may not be correct.

Use the following rest call to get the ListItemEntityTypeFullName

Uri: _api/web/lists/GetByTitle('People')?$select=ListItemEntityTypeFullName Headers: { "Accept": "application/json;odata=nometadata" }

Then examine the runtime output of the request to get the text for the ListItemEntityTypeFullName

@ekarim2020 I'm going to add to the pile. I'm getting the error of:
A type named 'SP.Data.Loan_x0020_ManagerListItem' could not be resolved by the model. When a model is available, each type name must resolve to a valid type.
The name of my list is "Loan Manager" so I added the '_x0020_"

Based on your post, here is the body of the http action:
{'__metadata':{'type':'SP.Data.Loan_x0020_ManagerListItem'},
'CurrentOwnerStringId':'',
'CurrentOwnerId':-1
}

The internal name of my people/group field is "CurrentOwner" without any spaces.

Any help that you could give would be greatly appreciated.

Hi @smorley

Confirm you have the correct ListItemEntityTypeFullName for the list "Loan Manager".

Please see section 5. How to CLEAR a People column using Power Automate of the post 🚹SharePoint People Column : How to Update and Patch in Power Automate and Power Apps and confirm you have the correct ListItemEntityTypeFullName for the list "Loan Manager".

This post shows how to CLEAR a People column using Power Automate:

Get the ListItemEntityTypeFullName

Clear a SINGLE select People column

Clear a MULTI-SELCT People column

Hope this helps.

Solved @ekarim2020 - there was a different internal list name. I did find out that you need _x0020_ if your name has spaces.
