¿Por qué el script de entrada de mi PSBT no tiene una clave de publicación?

Creé un PSBT para firmar un HTLC usando un P2WSH financiado, que deseo firmar con mi billetera xverse. Este es mi PSBT decodificado que he creado usando bitcoin-cli

Mi intención es seguir este ejemplo de conexión sats del documentos oficiales de sats connect para hacer la firma usando mi billetera xverse:

import {
  BitcoinNetworkType,
  RpcErrorCode,
  request,
} from "sats-connect";
    
const signPsbtOptions = {
    payload: {
      network: {
        type: 'Testnet
      },
      psbtBase64: `cHNidP8BAF4CAAAAAbPL7V1jyb+3R1UCjZ59ivvArJkc/+7bfxvA0QDjwJy+AAAAAAD+////AQAAAAAAAAAAIlEgmI+kZEmjRbl0oD6FTqJ7RKSipe+ZpSLIz0whDVrEu+MAAAAAAAEBK+gDAAAAAAAAIgAgpgjnxrbDIB0mCTFhbICxZdnAIvuWCkOZt5f+fZV3HMoBBVljqCBlLH3Gh9mMmIkwTtLkCMdLYR6GpAyqUcS0Px3VkTxc0Ih2qRTjmQVsTKY1caykT8LRGz/axpo34GcAsXV2qRTjmQVsTKY1caykT8LRGz/axpo34GiIrAAA`,
      allowedSignHash: btc.SignatureHash.SINGLE | 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);
  }

Sin embargo, cada vez que intento firmar el PSBT usando mi billetera xverse desde el navegador, aparece un 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

Esto me lleva a mi pregunta.

¿Por qué mi script de entrada PSBT no tiene una clave de publicación? En la sección de entradas del psbt decodificado, hay una sección scriptPubKey dentro del campo de entrada.
