published config file is not applied at all about payment HOT 6 CLOSED

You're right! Thank you for your support! Actually there were 2 classes called Payment. And I had added the other one (by PHPStorm autocomplete), instead of Payment facade.

from payment.

as the name loadDefaultConfig says, this method loads the default config of the package.
if you publish the configs using php artisan vendor:publish then your configs will be loaded instead of defaults.

your config file should be exists in config/payment.php path.

from payment.

Yes, I've already used that artisan command and the file does exist at config/payment.php. But anything I configure in config/payment.php is not applied including merchantId.

from payment.

run your project outside of docker and publish vendors, then check if every thing goes correctly or not and let me know about it.

from payment.

Dear friend, I tried running the project outside docker on production environment. The problem still exists. Could you please determine where in your code that published vendor config file is read?
This is the code I'm using for payment:

// create invoice
$invoice->amount(1000)
    ->detail('detail1', 'your detail1 goes here')
    ->detail('detailName2', 'your detail2 goes here');
// dd($invoice);
$orderAuditNumber = 10406;
$payment = new Payment();
dd($payment);

return $payment->callbackUrl(route('verify-order-payment', $orderAuditNumber))
            ->purchase(
                $invoice,
                function ($driver, $transactionId)
                {
                    // dd('inside callback');
                }
            )
            ->pay()
            ->render();

So, getting those invoice and payment objects shows that my merchantId is empty string and other configs are not applied, too. Also, another issue I saw was when I tried to run static function calls as suggested in github document like:

return Payment::purchase(
    (new Invoice)->amount(1000), 
    function($driver, $transactionId) {
	    // Store transactionId in database.
        // We need the transactionId to verify payment in the future.
    }
)->pay()->render();

Purchase function seems to be declared as a non-static function in driver files (like Zarinpal.php).

public function purchase()

But called statically in github document like the above call.

from payment.

you have done a mistake in your codes.
the Payment constructor accepts configs, so if you wanna to instantiate it, you MUST pass configs to it by yourself.
you have not fellow the docs, you should use Payment facade instead, then the package will handle configs itself.

change the codes like the below:

// Create new invoice.
$invoice = (new Invoice)->amount(1000);
// Purchase and pay the given invoice.
// You should use return statement to redirect user to the bank page.
return Payment::purchase($invoice, function($driver, $transactionId) {
    // Store transactionId in database as we need it to verify payment in the future.
})->pay()->render();

and about non-static function in driver files , i could say that Payment class handles calling methods and its not related to Zarinpal , this is a kind of Proxy pattern.
