Yes, I checked, but it didn't work with the essential plan. I asked the customer to switch to the plus plan, and with this plan, the order has already been uploaded.
I think it's a good idea to review that and indicate this in the instructions.
Thanks for the log option; I spent some hours looking for the problem. I found the debugger option, and the file is clear, help to resolve.
