Hi everybody,
running self-hosted IN v5.8.41-C156 on Ubuntu and since one of the latest updates (not sure which though - pretty sure it was working around v5.8.35 -ish) mailing quotes isn’t working anymore.
From what I can gather from the logs there seems to be an issue with the eInvoice module. Any ideas on how to fix it? Disabling eInvoices is a temporary fix, but obviously we would like to keep it enabled 
Here is the latest excerpt from the logs:
[2024-04-04 14:23:12] production.ERROR: Call to undefined method App\Services\Quote\QuoteService::getEInvoice() {"exception":"[object] (Error(code: 0): Call to undefined method App\\Services\\Quote\\QuoteService::getEInvoice() at /var/www/invoiceninja/app/Services/Email/EmailDefaults.php:324)
