Hello.
I'm a new user of ShipStation and I get the following error message when trying to print a shipping label.
"There was a problem with the request in its current state. (400, b78e6437-d117-4a47-9354-98830dd00f28)"
I don't know what that means and what I'm doing wrong or is missing in the configuration.
Please give me some help.
Thanks in advance, Stefan
PS: As additional information, I have a German DHL business account which is successfully linked to ShipStation.
