No PDF invoice generated if ODT template is used

[Movix]

Hello,

i tryed to put an ODT template in place.
I configured everything so that the conversion from ODT to PDF is done when generating the invoice (MAIN_ODT_AS_PDF and MAIN_ODT_AS_PDF_DEL_SOURCE). This works fine when generating the invoice manually.
Unfortunatly this do not work when the invoice is generated by sellyoursaas (invoice template). no conversion is done, so no PDF and no possibility for the customer to download his invoice.
What can i do to get this working ?

Best regards
Movix
