Here is my code I don't know where can i get tagId. Please help

I'm not sure I understand the issue at hand: idTag is being passed correctly to the request (although it's not necessary to override it again in the variadic function). Where does the error message come from? Is it a charge point running the same library? More information about the setup and conditions would help.
