Why is there no public key in my PSBT’s input script?

I created PSBT to sign HTLC using funded P2WSH which I want to sign with my Xverse wallet. This is the decoded PSBT I made. bitcoin-cli

It is my intention to follow the following sats-connect example from the official sats connect documentation to perform signing using my xverse wallet.

import 
  BitcoinNetworkType,
  RpcErrorCode,
  request,
 from "sats-connect";
    
const signPsbtOptions = 
    payload:  btc.SignatureHash.DEFAULT_ANYONECANPAY,
      broadcast: false, 
      inputsToSign: (
          
              address: "tb1pnz86gezf5dzmja9q86z5agnmgjj29f00nxjj9jx0fsss6kkyh03sjkqhpd",
              signingIndexes: (0)
          
      ),
    ,
    onFinish: (response) => 
      console.log('Signed PSBT:', response.psbtBase64);
    ,
    onCancel: () => alert('Signing canceled'),
  ;

  try 
    await signTransaction(signPsbtOptions);
   catch (error) 
    console.error('Error signing PSBT:', error);
  

However, whenever I try to sign PSBT using the xverse wallet in my browser, I get an error.

Input script doesn't have pubKey: 99,168,32,101,44,125,198,135,217,140,152,137,48,78,210,228,8,199,75,97,30,134,164,12,170,81,196,180,63,29,213,145,60,92,208,136,118,169,20,227,153,5,108,76,166,53,113,172,164,79,194,209,27,63,218,198,154,55,224,103,0,177,117,118,169,20,227,153,5,108,76,166,53,113,172,164,79,194,209,27,63,218,198,154,55,224,104,136,172

This leads to my question.

Why is there no public key in my PSBT input script? The input section of the decoded psbt has a scriptPubKey section inside the input field.
