Guzzly TypeError on invoice send

[theemstra]

Probably/possibly related to #47

On invoice send (invoice cron run or manual invoice creation invocation we get a GuzzleHttp error.
We run PHP 7.4.

Due to this issue the invoicing isn't working correctly, it's only invoicing half of the invoicelines and breaks off, even when re-running the invoice cron or manually invoking invoice job it will not run the missed invoice lines. Which means this is (for us) a very urgent issue.

We use your free Mollie gateway and also have the paid Mollie Recurring gateway installed.

Fixed with WHMCS 8 together with WHMCS Mollie Payments version 3.0. Closing for now, but thanks for reporting! 🚀
