Testing creating bulk offer, response tells me to check logs?

[erkrus-1]

Hi, I am trying to test my flow using postman. I am attempting to create an offer of an item that I created already through the bulk-create-item endpoint. I now want it to be on an offer (listing). I tried the request below but it returns an error to check logs (which I cannot do in ebays sandbox). Any help would be appreciated

this is my request body and url -
