Describe the bug

We have a SharePoint Online document library and for some documents the function "LoadListDataAsStream" runs into an error.
The problem seems to be related to the the metadata fields of the documents.
Unlike issue #1365 we don't use any image field data or location field data.

We call the function like this:

List.LoadListDataAsStream(new RenderListDataOptions()
{
    ViewXml = ViewXml,
    RenderOptions = RenderListDataOptionsFlags.ListData
});

The ViewXML looks like this:

<View>
	<Query>
		<Where>
			<In>
				<FieldRef Name='ID'/>
				<Values>
					<Value Type='Number'>40</Value>
				</Values>
			</In>
		</Where>
	</Query>
</View>

The error message is System.InvalidOperationException:

'The requested operation requires an element of type 'Object', but the target element has type 'String'.'

And the stacktrace of the error is:

at System.Text.Json.ThrowHelper.ThrowJsonElementWrongTypeException(JsonTokenType expectedType, JsonTokenType actualType)
at System.Text.Json.JsonElement.EnumerateObject()
at PnP.Core.Model.SharePoint.ListDataAsStreamHandler.TransformRowData(JsonElement row, IFieldCollection fields, Dictionary`2 fieldLookupCache)

at PnP.Core.Model.SharePoint.List.d__198.MoveNext()
at PnP.Core.Model.SharePoint.List.LoadListDataAsStream(RenderListDataOptions renderOptions)

Steps to reproduce

Since the error is specific to documents within our company and without knowing what the underlying problem is, I can't provide steps to reproduce.

Expected behavior

Loading the list items without an error.
