Hi,
This is working but, the email is not translated from the store locale which the order has been done.
From the backoffice, the email is translated but with command line, it's always send in english.

Do you have an idea how could I do that?

I am receiving this error message: We cannot create an empty shipment

Sorry I haven’t seen your message. I guess you solved it yourself in the meantime? :)

Can you show me a sample of an order that you’re trying to ship?

hi @fahu.
What do you mean by sample of the order? I just have a normal order collection and I tried to use your code in the loop. I have nothing special with my orders. They were created manual from the backend . Thanks :)
