Working swap example?

[RyanWilkins]

I can't get the Typescript swap example provided to work on devnet nor mainnet.

As given, using a devnet account with 1 SOL airdropped into it, I get the following error, presumably because the example pool has some token in it that my randomly generated account doesn't have.

Alternatively, trying on mainnet using the pool "3msVd34R5KxonDzyNSV5nT19UtUeJ2RF1NaQhvVPNLxL" I get various errors related to opening the AssociatedTokenAccounts. I tried manually opening the Wrapped SOL & USDC accounts but I still get an error related to the NATIVE_TOKEN pre-swap instruction. Removing the pre-swap instruction doesn't work either.
