Signing P2WSH PSBT with sats-connect: Need Help

I set up a funded P2WSH script which is an HTLC and now I'm trying to create a PSBT that another wallet will sign to withdraw the funds. However, I'm hitting a snag with this bitcoinlib-js error: Input script doesn't have pubKey. Not really sure what's going wrong or how to properly add the pubkey to the PSBT. Here's a detailed run-down of what I've done so far to create, fund, and (unsuccessfully) redeem the HTLC.
