Can't get OfferLogList

[josamho]

Hello !
I'm trying to get the OfferLogList of my submission package.

I already asked the CDISCOUNT support and they say to explain my problem here.

In the xml i get the OfferLogList code, but when with the code i get a object without the OfferLogList code (return an empty array.)

I attach the xml and the object !

image 1 : my request
image 2 : my result xml with the offerloglist not empty
image 3 : my result with php object and the OfferLogList empty ->
dump($getOfferPackageSubmissionResultResponse->getOfferLogList());
