laravel cashier's invoicePrice() method does not work properly

Question

I'm trying to use laravel cashier and stripe to generate an invoice instantly and charge the user, but it's not working. I'm referring to the example code snippets in the laravel-8 documentation to do this.

$user->invoicePrice('price_tshirt', 5, [
    'discounts' => [
        ['coupon' => 'SUMMER21SALE']
    ],
], [
    'default_tax_rates' => ['txr_id'],
]);

I created a product in my stripe dashboard and replaced 'price_tshirt' with the price ID of the product. The final code looks like this

if(!$user->hasPaymentMethod()){
    $user->addPaymentMethod($paymentMethod); //The $paymentMethod method is automatically generated
}

$user->invoicePrice('price_xxxxxxx', 1, [], [
    'description' => 'This is a virtual description',
    'currency' => 'usd',
    'receipt_email' => 'john@doe.com'
]);

After running the code nothing happened, I looked at my stripe dashboard and saw nothing. My goal is to charge users and generate invoices for them so that I can access those invoices later via code like this $user->invoices()

Note: I was using $user->charge(100, $paymentMethod); and it worked perfectly but didn't generate any invoice, then I decided to use $user instead ->invoiceFor() method, this method only generates an invoice, but the user is not charged. I decided to change again and use $user->invoicePrice() but this method didn't work at all. I need to let users manage their invoices after payment, but I can't find a method that helps me do this (generate invoices and charges). I don't know what I'm doing wrong, please help.

It sounds like the problem is that laravel uses a "pending_invoice_items_behavior" that is disabled by Stripe as "include_and_require", so the items are excluded by default.

I tried adding a new parameter like this.

$user->invoicePrice('price_XXXXXXXXXXXXXX', 5, [], [
    'pending_invoice_items_behavior' => 'include',
]);

However, I also encountered currency errors because my users were previously charged in CAD when I tried the product in USD (big thanks to whoever posted this question before!!).

But when I create a new user with a pre-existing currency instead of a customer, it works.
