Got the transaction HASH, but the transaction was not successful about php-erc20

Sometimes if nonce will be wrong, created TX built and broadcast successfully, but blockchain does not accept that.

A nonce will be considered wrong when:

1. An address has too many transactions happening at the same time or has pending transactions
2. The node that is used to retrieve information is not updated

For fetching the current nonce, the code using the below code, you can rewrite your own transferFrom function and provide the correct nonce. (that may be saved in DB!)

public function transferFrom(string $spender, string $from, string $to, float $amount, string $gasLimit = 'default', string $gasPrice = 'default')
{
    $amount = Number::scaleUp($amount, $this->decimals());
    $data   = $this->buildTransferFromData($from, $to, $amount);
    $nonce  = Number::toHex($this->getEth()->getTransactionCount($spender, 'pending')); //<--this line
    if (strtolower($gasLimit) === 'default')
    {
        $gasLimit = $this->getGasLimit('transferFrom');
    }
    if (strtolower($gasPrice) === 'default')
    {
        $gasPrice = $this->getSafeGasPrice();
    }

    return (new TransactionBuilder())
        ->setEth($this->getEth())
        ->to($this->contractAddress)
        ->nonce($nonce)
        ->gasPrice($gasPrice)
        ->gasLimit($gasLimit)
        ->data($data)
        ->amount(0)
        ->build()
        ;

}

hello, i try to get getTransactionCount(), all get 1, $spender = '0xdac17f958d2ee523a2206206994597c13d831ec7';
$nonce = Number::toHex($this->getEth()->getTransactionCount($spender));// result 1
$nonce = Number::toHex($this->getEth()->getTransactionCount($spender, 'pending'));// result 1

Do I just need a random nonce value, such as 123456, or does the nonce have to be a value that can be obtained from a specified method?

Wallet A authorized wallet B, and the contract used at the time of authorization was 0xdac17f958d2ee523a2206206994597c13d831ec7
When getting the nonce, passed in is the A wallet address or the contract address 0xdac17f958d2ee523a2206206994597c13d831ec7 ?
$nonce = Number::toHex($this->getEth()->getTransactionCount($spender, 'pending'));

I don't know much about this, I'm trying to learn recently, please help

public function transferFrom(string $spender, string $from, string $to, float $amount, string $gasLimit = 'default', string $gasPrice = 'default')
$gasPrice
When this parameter is not passed in, this error will be prompted. If I pass in 700000, it can be executed correctly. Does this need to be set manually?
insufficient funds for gas * price + value
Is it because of this reason that the TX cannot be obtained by query?

This address 0xdac17f958d2ee523a2206206994597c13d831ec7 is USDT contract, its connot be used as spender.

Spender should be one of your wallets.

nonce is a sequential number starting from zero.
nonce for address with no transaction is zero, and for each transaction, this number increased.

In script $gasPrice has a default value, but in some case (as your) need to be set manually.
