index.ts lines 46 and 47: Changed second parameter in addTransaction calls to makeBasicAccountTransactionSigner(signer) instead of just sender

1. The code for coding challenge Convert sender to TransactionSigner. #4 is failing with the error TypeError: signer is not a function
2. On lines 46 and 47 of the original code, sender, an account object, is being used as the second parameter for the addTransaction call. This parameter needs to be a signer object. The algo SDK function makeBasicAccountTransactionSigner can be used to get the signer for the sender object (in other words, the second parameter in both calls should be changed to algosdk.makeBasicAccountTransactionSigner(sender)).

Hi Chris - I was hoping you might be able to help me, I'm getting a "Your claim has been rejected by Github verifier on this PLAUS! No matching PR, or PR is already claimed!" error when I try to claim my NFT for coding challenge #4. I have successfully claimed the NFTs for the other challenges.
