Patch Request to SharePoint List --- People Picker Field

KNIME Analytics Platform
1

I am struggling to update a SharePoint People Picker field (in combination with a few others fields) in SharePoint using the Graph API capabilities and a Patch Request Node. I can get the normal fields to update but not the People Picker one. I keep either getting an error or it says it was successful and the field remains blank.

For the data below I get a 200 response but the People Picker remains blank. I have tried NameLookupId as the field name and put the email versus the People ID value from the User Information List.

I am at the loss, any help would be appreciated.
This is the URL:

This is the body of the JSON in the request:

"{
““Name”” : 23,
““Markets”” : ““Ireland;United Kingdom””,
““WWID”” : 30500665,
““Status”” : ““A””,
““Function”” : ““Legal””,
““Level”” : ““Manager””,
““Position”” : ““Officer””,
““Email”” : ““maypar@mycompany.com””,
““Region”” : ““EMEA””,
““LastUpdatedPostgres”” : ““2025-06-04"”
}”

best to ask about the Microsoft SharePoint Graph API in the Microsoft Support Forums.
This is the Knime support forum.

Thanks, I have done that as well. I was hoping someone else may have tried something similar and perhaps the formatting or the way to node was configured might be the issue here.
