pdfInvoice() function

[Qhiliqq]

Hi together,

I use the pdfInvoice() function in a hook to send invoices to my bookkeeping.
Since my update to PHP 8.1 and WHMCS 8.7.3 the function just creates a blank pdf.

Any ideas?

function will be called like:
 

$pdfdata = pdfInvoice($invoice_id);
file_put_contents($invoice_id.'.pdf', $pdfdata);

Regards
Philipp

Or is there a other function to generate invoice pdfs in a hook/script?

So after a few weeks the same error still exists...
If I run the hook again, the PDF will be created as usual.
If the hook runs first time, a empty PDF will be generated...

I try to use the pdfInvoice function in a InvoicePaid hook.
This way it should generate a pdf invoice after marking the invoice as paid.
This worked before upgrading to PHP8.1 and  WHMCS 8.7.3 as a charme.

Any ideas?
