how to clear the value of the column of person type

[crliu]

I want to clear the value of the column of person type by submitting the SharePoint HTTP request, but I set this item as null in JSON, and the value is not cleared after running. What should I do?

I set it to ["inv_tnt": - 1], execute and report an error:

While trying to read the value of the navigation property, the 'privileevaluue' node that contains non null values was found, but it was intended to read the 'fiertertivevalue' node containing the 'startarray' node, 'startobject' node, or null value.

Hi @crliu ,

Please make sure inv_tnt is your column's internal name.

It should be inv_tntId : -1. You should append Id in internal name of the column.

Thanks,

Vivek
