How to change the gameplay tag so using python

I get the gameplay tag from the table, then I want to set it by default in my blueprint class, but it doesn’t work, tell me how do I do it?

item_slot = unreal.PythonDataTableLib.get_property_as_string_at(dt_melee, row_id= row_num, column_id= 5)
blueprint_class_default.set_editor_property(‘ItemSlot’, unreal.GameplayTag(item_slot))

LogPython: Error: TypeError: NativizeProperty: Cannot nativize ‘str’ as ‘Value’ (StructProperty)
LogPython: Error: TypeError: NativizeStructInstance: Cannot nativize ‘str’ as ‘GameplayTag’
LogPython: Error: Exception: GameplayTag: Struct has 0 initialization parameters, but the given sequence had 31 elements
