Invalid project Option specified, Cannot validate upload : error 400

we sent a translation request in Test env and receive this error   Invalid Project Options specified. Cannot validate upload (error 400)

Tenant : 591314

Request reference: 44692-InvPolicy-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

project option id : "61603a6969ac9a2b8fddfe9b" for en-GB language (the same one for prod env is used)

after analyses in our side we found thoses response since February 2024

Is there something changed in non prod env?

Thanks in advance,
