Unable to sign messages using EthereumPrivateKeyProvider

Unable to sign messages using EthereumPrivateKeyProvider.

I'm trying to get Provider (which can sign and send transaction) from private key using @web3auth/ethereum-provider package, but I'm able to get provider but getting error while signing the message using that private key.

To Reproduce

`import { EthereumPrivateKeyProvider } from "@web3auth/ethereum-provider";
import type { SafeEventEmitterProvider } from "@web3auth/base";
const signEthMessage = async (provider: SafeEventEmitterProvider): Promise => {
const web3 = new Web3(provider as any);
const accounts = await web3.eth.getAccounts();
// hex message
const message = "0x47173285a8d7341e5e972fc677286384f802f8ef42a5ec5f03bbfa254cb01fad";
const signature = await web3.eth.sign(message, accounts[0]);
return signature;
};

(async () => {
const provider = await EthereumPrivateKeyProvider.getProviderInstance({
chainConfig: {
rpcTarget: "https://polygon-rpc.com",
chainId: "0x89", // hex chain id
networkName: "matic",
ticker: "matic",
tickerName: "matic",
},
privKey: "4c0883a69102937d6231471b5dbb6204fe5129617082792ae468d01a3f362318",
});
const signedMessage = await signEthMessage(provider);
})();`

Steps to reproduce the behavior:

1. Run above code to sign message using private key.

Expected behavior
