Syntax error, unexpected token ")" when sending mail in laravel 8-CodePudding

I know the title seems familiar but hear me out...

My code works locally when I try to send out an invoice via email and the email gets sent. However, I deployed the same code to production on ec2 and got this error;

My controller looks like this...

public function invoice_send(Request $request, Invoice $invoice)
{
    Mail::to($request->to)->queue(new NewInvoice($invoice, $request));

    return redirect()->route('invoice.show', $invoice);
}

The vendor folder is the only thing that is different between production and development servers so I deleted the vendor and run composer install again but that didn't solve anything.

Any ideas?

You are queueing the email. It could be that an old version of your code is used for processing the queue. You can have a look at the Laravel documentation about this. Try restarting the queue-worker if configured.

I resolved this by downgrading my PHP version from 8.1.8 to 8.0.21.
