new ethers.JsonRpcProvider('http://127.0.0.1:8545')

Local hardhat test network

npx hardhat console

const hardhat = new ethers.JsonRpcProvider('http://127.0.0.1:8545')

                    JsonRpcProvider {}

it doesn't fetch the json object and its properties, instead of that it is only showing me as the output ( JsonRpcProvider {} )

it works totally fine in ethers 5.7.2 library ( no issue so far there)

how can i fetch the all json object and its propeties.

Welcome to Node.js v16.17.0.
Type ".help" for more information.

const hardhat = new ethers.JsonRpcProvider('http://127.0.0.1:8545')
undefined
hardhat
JsonRpcProvider {}

I believe it's logging an empty object for the base object because v6 uses Proxy objects, so the console can't directly print the underlying object's properties.

If you just want to see a list of all the properties you can call, you can loop through the prototypes with Object.getPrototypeOf and get all properties using Object.getOwnPropertyNames.

For example:

function logAllProperties(obj) {
  if (Object.getPrototypeOf(obj) === null) {
    return;
  }
  console.log(Object.getOwnPropertyNames(obj));
  logAllProperties(Object.getPrototypeOf(obj));
}

logAllProperties(hardhat);
