Unable to submit a Multiagent transaction in the demo next.js app

[jmintuitive]

Found the bug while updating the standardWallet example here: #356

There is a bug I found when testing that the Multiagent flow fails on Submit in particular. I'm not entirely sure why - but it seems that there is an INVALID_AUTHENTICATOR error.

Steps:

1. Connect a wallet
2. Click through the multiagent steps
3. The app will crash (or display an error) when trying to submit the multiagent transaction.

Hi! Which version of Next.js are you using? Because I just can't run the app with the error "Module not found: Can't resolve 'aptos'" inside this package.

I'm not sure what version of Next.js, but that error is probably from a missing dependency for aptos. Maybe do pnpm add aptos?
