I am trying to retrieve offers detail using seaport API for a given asset contract for a given token ID but it returns null for the signature field.
My understanding is that this signature is the signature from the offerer. and if I wanna accept the offer by calling the seaport fulfillBasicOrder_efficient_6GL6yc function or any other similar function to fulfill the order directly via etherscan I need to pass the signature.
My question is why is testnet API returning null for offer that is created and I can see on opeansea?
Also, what is the exact JSON format for an order that the offerer sign, I tried to create this signature locally for testnet by using mycrypto/sign-message
I tried using parameter JSON (returned by API call) and stringify it but couldn’t pass fulfillBasicOrder_efficient_6GL6yc function call transaction-simulator it fails at Seaport. _assertValidSignature
