"Cannot estimate gas; transaction may fail or may require manual gas limit" when deploying the contract

Hello @pravinva , using your app to create private key worked flawlessy
Thanks!

[pravinva]

Can you check (perhaps on etherscan.io) if you've added the test eth to the correct wallet. it should be in the sending wallet and not the receiving one which is used for receiving the minted token. (i,e the wallet associated with the pvt key stored in ssm)
ethers library does not seem to provide better handling for such errors, but from experience, this error is likely because you may have not added token to the correct wallet

Hello,
Yes as you can see i've got the eth here
for what concern the private key I had to use the following script to retrive it

var keythereum = require("keythereum");
var datadir = "C:\\Users\\xxx\\AppData\\Local\\Ethereum\\rinkeby";
var address= "0x1Eccba5f2133bEBD720B291ab269b51ba426Ee66";
const password = "MyPWD!!!";

and I got a string as bab6b0f5cf16287ed6042386f44329a647bb4c9e3772776244484d996fc36c38 is this one I have to put in the SSM?

I got a different error now... no more error on gas fee but got

{"Error":{"code":-32000,"transaction":{"type":2,"chainId":4,"nonce":0,"maxPriorityFeePerGas":{"type":"BigNumber","hex":"0x9502f900"},"maxFeePerGas":{"type":"BigNumber","hex":"0xc58369ea"},"gasPrice":null,"gasLimit":{"type":"BigNumber","hex":"0xc350"},"to":null,"value":{"type":"BigNumber","hex":"0x00"},"data":"","accessList":[],"hash":"0x864a7a6c60192362d842d9d2a407351c2f94814bf82a652ec10823b6d6640ad8","v":0,"r":"0x60a01e3e991f69f1de6a3ec1c8f330b28bad2af0fce157cd121eb4e0025e7220","s":"0x3fb2a4e6d8bfd3ad00b95a323beddac396972935f988e0edc96a6d57fed747e1","from":"0x1Eccba5f2133bEBD720B291ab269b51ba426Ee66","confirmations":0},"transactionHash":"0x864a7a6c60192362d842d9d2a407351c2f94814bf82a652ec10823b6d6640ad8"}}

What is -32000?

Thanks

Debugging ethers library errors is beyond the scope of this activity. I have uploaded a zip file with an utility to create pvt keys and corresponding wallet address under misc/create-eth-wallet.zip. Please unzip it, and run the shell utility provided to generate the credentials and then follow instructions

Pravin thanks for your reply, now I'll try your utility, but what I'm trying to understand is if it's an error on my side (I've followed literally the tutorial) or if there's something I'm missing Thanks
