这个错误可能是因为在使用`with`语句时，没有指定需要使用的游标类型。可以将`with`语句中的`UpdateCursor`改为`arcpy.da.UpdateCursor`并指定游标类型，例如：

with arcpy.da.UpdateCursor(target_feature, [target_field, join_field], sql_clause=(None, "ORDER BY OBJECTID"),) as cursor:

此外，还需要将导出结果的代码修改为：

arcpy.CopyFeatures_management(target_feature, arcpy.GetParameterAsText(5))

即使用`GetParameterAsText`获取输出路径，并将输出结果拷贝到指定路径。
