Lesson 8: Fund function problem 'Internal JSON-RPC error.'

[Aishwaria8786]

I am facing this problem in browsers console.
{code: -32603, message: 'Internal JSON-RPC error.', data: {…}, stack: '{\n "code": -32603,\n "message": "Internal JSON-RP…eogaeaoehlefnkodbefgpgknn/background-3.js:1:10469'}
Fund function wasn't working before and after creating a new network Hardhat Localhost and importing Eths.

@Aishwaria8786 check your hardhat node terminal, it will show you the revert error thrown by your smart contracts.

What should I do now?

@Aishwaria8786 It reverts Error: Transaction reverted: but does not exactly tell what is error due to not recognizing the function.
