laravel cashier invoicePrice() doesn't work

Question

I'm trying to use laravel cashier with stripe to generate invoice and charge users immediately but it doesn't work. i'm taking reference from the sample code snippet 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); //$paymentMethod method was genearated
}

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

After running the code nothing happened, i looked at my stripe dashboard, i saw nothing. my goal is to charge users and generate invoice for them so that i can access those invoices later on in my application by doing something like this $user->invoices()

NOTE: i was previously using $user->charge(100, $paymentMethod); which works perfectly but doesn't generate any invoice, then i decided to change and use $user->invoiceFor() method, this method only generated an invoice but the user wasn't charged. I decided to change again and use $user->invoicePrice() but this method didn't do anything at all. It is required that i let users manage their invoices after payment but i cannot find a method that can help me do that (generate invoice and charge). I don't know what i'm doing wrong, please help.

Sounds like the issue is laravel using a "pending_invoice_items_behavior" of "include_and_require" which has been disabled by Stripe. So items are getting excluded by default.

I tried including a new parameter like this.

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

I also however experienced the currency error, as my user had previously charged in CAD when I was trying a product in USD (Huge thanks to whoever posted that.!).

But when I created a new user instead of customer with a preexisting currency, it worked.
