The issue in your deploy.js file is due to a typo in accessing JsonRpcProvider. Instead of ethers.provider.JsonRpcProvider, it should be ethers.providers.JsonRpcProvider. |

For those that still want to use version ^6.0.8 that is version 6.0 and above ethers has a documentation for it
https://docs.ethers.org/v6-beta/getting-started/
instead of downgrading to a lower version, in the version 6 and above all you have to do is this
const provider = new ethers.JsonRpcProvider("in here will be your ganache RPC server");
instead of
const provider = new ethers.provider.JsonRpcProvider("in here will be your ganache RPC server");

The fix for me was to downgrade "ethers" to version 5.4.. you can remove previous version by running |

There is no need to to downgrade ethers. Simply replace - const provider = new ethers.providers.JsonRpcProvider("HTTP://127.0.0.1:7545");
+ const provider = new ethers.JsonRpcProvider("HTTP://127.0.0.1:7545"); |
