I see you try to implement the metamark functionality in your HTML/Javascript application. Here is an article that addresses the problem with the beginning:
Metask problem: Can anyone tell me where the problem is?
As a developer, I have encountered numerous errors when I implemented the metamark functionality in my projects. One of the most common problems is related to the “accounts” that is empty or null, which can cause unexpected behavior or errors.
In this article,
Why Getaccount () returns indefinitely
When this method
Here is an example of what could happen:
`Javascript
The ASYNC GETACCOUNT () function {
Try {
Constururi = await ethereum.request ({method: ‘eth_requestaccounts’});
console.log (accounts); // Exit: [{address: “0x …”}, …]
} Catch (error) {
Console.error (error);
}
}
`
The function tries to access the variable "accounts". If Metask returns a number of accounts, it will be attributed to the variable "accounts". However, if Metask cannot find accessible wallets or return null/indefinite,accounts will remain undefined.
** Why is Getaccount ()?
There are several reasons why Getaccount () could come back null:
1.
- wallet is not authorized :
- METASK Version Misprint :
troubleshooting steps
Returning or undefined, try these troubleshooting steps:
1.
- Check your wallet authorization :
- Update to Metask Compatible version :
- Disable and re-frame Metask : Temporarily disable Metask and then re-reject it to see if the problem is related to access permissions.
Example: Implementation of self-transactions with Getaccount ()
Getaccount (), you can store the returned accounts in a variable and you can use them for your translation. Here is an example:
Javascript
Async function maketransction () {
Try {
Constururi = await ethereum.request ({method: ‘eth_requestaccounts’});
console.log (accounts); // Exit: [{address: “0x …”}, …]
// use the returned accounts for your transaction …
} Catch (error) {
Console.error (error);
}
}
// call maketransction () every time you want to send an automatic transaction
Setinterval (Maketransction, 10000); // send self-transactions every minute
`
Every minute using ‘setinterval ().
`The function that turns null or undefined. Good luck with the implementation of Metask functionality in your project!
