revert reason not know in ganache/ethers.

Hi @zemse @ricmoo

I'm creating this issue once more as it's been hell dealing with this.

I'm using ethers.js and RPC provider is ganache on localhost.

When I do the below(note that I intentionally revert in function() with custom error: revert Blabla()

try {
  await contract.function()
  }catch(err) {
     console.log(err.data.data)  // prints undefined
     console.log(err.error.error.error.data)  // prints undefined
  }

The only defined thing is err which only says error: Error: VM Exception while processing transaction: revert

I can't seem to get the revert message which is Blabla.

It could be ganache endpoint, but not really sure. Thoughts ?

Are you using v5 or v6? In v6, more effort has been made to extract the error. You can also use provider.on("debug", console.log) to see what the server is responding with.

@ricmoo OKay, So i'm using @ethersproject (5.7.0) with its specific packages.

1. Seems like If my provider is infura - goerli, I can get the revert data reason(hex) in: err.error.error.error.data;
2. But if I use ganache on localhost, http://127.0.0.1:7545, i can't get error message other than execution reverted. I looked into the whole error message, but it doesn't contain it.

Could this be ganache and why ?
