truffle에서 cypress 콘솔에 접근하려고 하면 이런 에러가 납니다. deploy할 때도 마찬가지입니다.

truffle-config.js 내용은 아래와 같습니다.

cypress: {

```
  provider: () => {

    const option = {

      headers: [

        {

          name: "Authorization",

          value: "Basic " + kas,

        },

        { name: "x-chain-id", value: "8217" },

      ],

      keepAlive: false,

    };

    return new HDWalletProvider(

      privateKey,

      new Caver.providers.HttpProvider(

        "https://node-api.klaytnapi.com/v1/klaytn",

        option

      )

    );

  },

  network_id: "8217", //Klaytn baobab testnet's network id

  gas: "850000000",

  gasPrice: "25000000000",

},

```

baobab은 접속이 잘 됩니다.

자답입니다.  
value: "Basic " + kas, 이 부분에서 kas에 이미 Basic xxx…으로 값이 들어있어서  
value가 Basic Basic xxx… 이렇게 들어가는 문제였네요.
