I am trying to create multiple sell orders for my NFTs on the rinkeby testnet. I am using the script provided by OpenSea from this repo called sell.js

The issue is after I run the script, the method createSellOrder seems to run because I get the following output on my terminal but nothing else appears or happens.

The first two lines are my own logging and the third line is what I guess is from createSellOrder.

My question is, what is the expected outcome/output of createSellOrder and how can I know it succeeded? For me it just prints the last line: creating proxy for acc... and stops.

When I check opensea, it doesn't have my nfts listed for sale so it obviously didn't work...
