What are you actually trying to do?

layer.pendingFields() returns QgsFields instance, which basically acts
as a list of QgsField instances (attribute definitions). Then, you are
trying to assign an attribute value (QVariant) to a field - that's
clearly an error and it is reported correctly. Probably you want to
copy the attributes to another feature?
