@sandeepnarahari49 Thanks for your recent communication.

Can you please share your Web3auth Initialization snippet and implementation code? Which framework are you using React, nodeJS, web, Anrdoid etc? Please provide more information.

Hi @vjgee

```auto

const privateKey = fs.readFileSync("privateKey.pem");
const privateKeyProvider = new EthereumPrivateKeyProvider({
config:{
chainConfig:{
chainId: “0x1”,
rpcTarget: “https://rpc.ankr.com/eth”,
displayName: “Ethereum Mainnet”,
blockExplorer: “https://etherscan.io”,
ticker: “ETH”,
tickerName: “Ethereum”,
}
}
})
const web3auth = new Web3Auth({
clientId: process.env.WEB3AUTH_CLIENT_ID,
web3AuthNetwork:“testnet”,
})
web3auth.init( privateKeyProvider );
export async function connect(user:any, key:boolean) {
try{
    const web3authsfaProvider = await web3auth.connect({
        verifier, 
        verifierId: user.id?.toString(),
        idToken:jwt.sign({
            sub : user.id?.toString(),
            name: user.name,
            aud: "urn:api.uat.autonomy.network",
            iss: "https://api.uat.autonomy.network",
            iat : Math.floor(Date.now() / 1000),
            exp: Math.floor(Date.now()/1000) + 60 * 60,
        },
        privateKey,
        { algorithm: "RS256", keyid: "1bb9605c36eYXV0b25vbXk69386830202b2d" }
        )
    })

    const ethPrivateKey:any = await web3authsfaProvider.request({method:"eth_private_key"})
    const wallet = new Wallet(ethPrivateKey)

    if(key){
        return ethPrivateKey
    }
    else return wallet.address

}catch(e){
    console.error(e)
}

```

We are using Telegram id as verfierID and dependencies are

```
"@web3auth/ethereum-provider": "^7.0.4",
"@web3auth/single-factor-auth": "^7.0.1",

```

I have the same error using the Solana blockchain and @web3auth/node-sdk. I logged in on the frontend with the Unity SDK, then I make a call to a node.js server passing on the Web3Auth JWT Token and the user email as argument:

```auto
const web3auth = new Web3Auth({
    clientId: CLIENT_API, // Get your Client ID from Web3Auth Dashboard
    web3AuthNetwork: "sapphire_devnet", // Get your Network from Web3Auth Dashboard
});
const solanaProvider = new SolanaPrivateKeyProvider({
config: {
chainConfig: {
chainNamespace: CHAIN_NAMESPACES.SOLANA,
chainId: “0x1”, // Please use 0x1 for Mainnet, 0x2 for Testnet, 0x3 for Devnet
rpcTarget: myRPC,
wsTarget: “”,
displayName: “Solana Mainnet”,
blockExplorer: “https://explorer.solana.com”,
ticker: “SOL”,
tickerName: “Solana”,
decimals: 9,
},
},
});
await web3auth.init({ provider: solanaProvider });

```

The error message looks like this:

```auto
App 17452 output: SomeError: Unable to resolve enough promises.
