TypeError: Cannot read property toString of undefined while trying to signTransaction

[jsoneaday]

I'm running the code below with some logs and at the point of running wallet.signTransaction it fails with the error given in the title. The entire error below. The code to get connections and setup and connect the wallet all work. As does the setup of the Transaction itself.

I am running:
devnet
solana: 1.6.6
sol-wallet-adapter: 0.2.0
web3.js: 1.9.1

react_devtools_backend.js:2557 Failed TypeError: Cannot read property 'toString' of undefined

  })
);
transaction.recentBlockhash = (
  await connection.getRecentBlockhash()
).blockhash;
transaction.feePayer = wallet.publicKey;
console.log("finished setting up transaction");
