JsonRpcProvider does not exist for ethers.js version ^6.0

[rsbassi9]

I used ethers.js version ^6.0 but got an error saying "JsonRpcProvider does not exist". after going through stackOverflow, there seems to be a bug with the beta version of ethers.js version^6.0.

I downgraded to version 5.6.2 (the same as Patrick), but now I get the following error:

'''
Deploying, please wait...

I'm not too sure how to solve this. my RPC URL and wallet addresses are correct from Ganache. anyone know where the connection error is?

You can try the ganache command line interface(cli), on your command line type yarn add ganache to install it
Then after the installation, check to see its installed by typing this -> yarn info ganache
To run ganache type -> yarn run ganache
Copy the private key and paste it here -> const wallet = new ethers.Wallet(
"0x8c3df02dbaf50bac7478ed57bc37e08334a5aba5f3fe6f8d3537473c9d6452be",
provider
);
JsonRpcProvider -> const provider = new ethers.providers.JsonRpcProvider(
"http://127.0.0.1:8545"
);
and the id is this -> 1337

I managed to fix the error by changing the server connection in Ganache and specifying WSL. Now I get the following error:

Deploying, please wait...
<ref *1> Error: cannot estimate gas; transaction may fail or may require manual gas limit

I am trying to increase my gas limit to try and see if this works, but so far none of the manual limits I have set get rid of this error...

[rsbassi9]

To fix this, specify the gas limit in the code:

const gasLimit = 5000000;
const contract = await contractFactory.deploy({ gasLimit })

Transaction was approved!

changed the server connection in Ganache and specified WSL.

specified gas limit within contract to eliminate:
<ref *1> Error: cannot estimate gas; transaction may fail or may require manual gas limit
