Seaport giving an error when listing the nfts

Hey there, I am trying to list 3 nfts to opensea using seaport.js and the opensea conduit key. I used the first example for the request in the github repository of seaport.js. The error happens when i try to fullfill the order using the connected address as the accoundAddress.

Hi @marksSweden ,

Is there any more text parts to the error that get included, like a code? Or simply only the text you shared.

Have you defined the current web3Provider correctly?

Perhaps the variable fulfiller is equal to undefined when the function is started. Can you check it in the debugger or by simple output to the console?
