Michael Law said about 7 years ago on Decoding and Interacting with Barcodes :

I was just about to ask you if it was throwing the error because I'm not passing the ticket_id. I'm not the best with jQuery so I didn't know if the client required that, although as I type it this makes sense that it would.

What do you mean by "pass it into the data attribute"?

Are you saying that the client is throwing the original error I posted because it's trying to find the order, but doesn't have the ticket_id?
