Network mismatch. Provided network \"testnet\" does not match project network \"sapphire_devnet\""

[uditverma150]

I am unable to configure my web3auth setup.

const clientId = process.env.WEB3_AUTH_CLIENT_ID || ‘’;

const chainConfig = { //ChainList we are using sepolia network for this
chainNamespace: CHAIN_NAMESPACES.EIP155,
chainId: ‘0xaa36a7’,
rpcTarget: ‘https://rpc.ankr.com/eth_sepolia’,
displayName: ‘Sepolia Testnet’,
blockExplorerUrl: ‘https://sepolia.etherscan.io’, //transaction history of network
ticker: ‘ETH’,
tickerName: ‘Ethereum’,
logo: ‘https://assets.web3auth.io/evm-chains/sepolia.png’,
}

const privateKeyProvider = new EthereumPrivateKeyProvider({
config: {chainConfig},
});
const web3Auth = new Web3Auth({
clientId,
web3AuthNetwork: WEB3AUTH_NETWORK.TESTNET,
privateKeyProvider
});

If you find any errors then please help in resolving

Hey Udit,

Thanks for reaching out! It looks like you’re experiencing a network mismatch issue in your Web3Auth setup. Let’s go through your setup details:

• SDK Details: Plug n Play
• Issue: “Network mismatch. Provided network ‘testnet’ does not match project network ‘sapphire_devnet’”

The error message indicates that the network specified in your Web3Auth configuration (testnet) doesn’t match the project’s network setting (sapphire_devnet). Here’s what you might want to check or do:

1. Check Your Project’s Network Setting:

   • Ensure that your project’s network setting in the Web3Auth dashboard matches your code’s configuration. It seems you’re targeting the Sepolia Testnet. Confirm this in your project settings.

2. Update Your Code Accordingly:

   • If your project should indeed be on the Sepolia Testnet, ensure your project settings reflect this. Alternatively, if sapphire_devnet is correct, update your code to match that instead.

3. Client ID Configuration:

   • Double-check that the client ID being used corresponds to the correct network configuration.

Please let me know if you need further assistance after checking these settings! If you still encounter issues, provide a screenshot of your configuration from the Web3Auth dashboard, and we can delve deeper.

Hope this helps!

Hey @uditverma150,

The error message indicates that the network mismatch is due to your Web3Auth setup using TESTNET, while your project on the Web3Auth dashboard is configured for sapphire_devnet.

To resolve this, please update your web3AuthNetwork from:

web3AuthNetwork: WEB3AUTH_NETWORK.TESTNET

to

web3AuthNetwork: WEB3AUTH_NETWORK.SAPPHIRE_DEVNET

This should align your code with your project’s network configuration.
