Asinincrica GetPENDINGTRANSATIONS () {) function

Attempt {

Const TXCOUNTS = ABSWIT Web3.eth.gettransationCount (Useraddress);

return TXCOUNTS;

} Catch (error) {

console.error (error);

When usingEth_gettransationCount ', you may find errors or limit problems. Here's how you can change your code to manage these:

Javascript

Asinincrica GetPENDINGTRANSATIONS () {) function

Const TXCOUNTS = ABSWIT Web3.eth.gettransationCount (Useraddress);

// Check transactions counting errors

IF (TXCOUNTS <1) {// If there are no pending transactions, return 0

console.error (“no suspended transaction found”);

Return 0;

}

return TXCOUNTS;

}

// call the function

GetPenDingtransactions (). Then ((txcounts) => console.log (txcouns));

`

This code will record an error if there are no pending transactions and will see a "0" instead.
