07 Feb Metamask: Metamask doesn’t switch to local node, no error message
Metamask problem with local node switching
I am seeing a common problem when users try to switch their metamask instance from a remote network to a local hardhat node using Wagmi.sh. The dialog box that appears after confirming the switch usually does not display any error message, leading to frustration.
The question:
When you use UsAwitchnetwork with Wagmi.sh and Metamask on a remote network, the dialog box calls for confirmation to move from the remote network to the local hardhat. However, it is not displaying any error message or indicating that the switch was successful. This can lead users to believe that the problem is solved without really being aware of what went wrong.
The solution:
To solve this problem, you need to add a check to the success of the switch operation and display an appropriate error message if you fail. Here is an example code for you to start:
`JavaScript
CONST USAWITCHNETWORK = Async ({Type, Network}) => {
to try {
awaits usawitchnetwork ({type, network});
} catch (error) {
console.error (‘error change to the local hardhat node:’, error);
Alert (‘error change to the local hardhat node. Check your connection and try again.’);
}
};
`
In this code snippet, we are using the Try-Catchblock to capture errors that may occur during the switch operation. If an error occurs, we record it on the console and display a friendly error message with an alert box.
Alternative Solution:
You can also use WAGMI.sh internal support for network switching using theUsawitchnetwork ‘function on your Hardhat configuration file (hardhat.config.js). Here is an example:
`JavaScript
Consta {ether} = requires (‘wagmi’);
MODULE.EXPORTS = {
// …
Async Configure ({env}) {
CONST REDE = ENV.NETWORK;
to try {
CONST MATASKINSTANCE = Wait for ashers.getSigner ();
if (network === ‘metamask’) {
awaits uswitchnetwork ({
Type: ‘Switch’,
network,
});
}
} catch (error) {
console.error (‘error change to the local hardhat node:’, error);
Alert (‘error change to the local hardhat node. Check your connection and try again.’);
}
},
};
`
In this example, we are using the Ethers' library to get a subscriber instance based on the current network. Then we use theUsawitchnetwork function to switch to the local hardhat node.
Conclusion:
By adding error check error and friendly error messaging display, you can solve the metamask problem do not switch to the local hardhat node after using Usawitchnetwork. This should improve the user’s overall experience and help avoid frustration.
