Cant send New Order Emails etc

[cmvika]

Hello, Im getting this error:

[2017-11-07 23:50:53] main.ERROR: Notice: Undefined index: invoice in /is/htdocs/.../vendor/eadesignro/module-pdfgenerator/Model/Email/SenderBuilder.php on line 105 [] []
[2017-11-07 23:52:38] main.ERROR: Unable to send mail. [] []
[2017-11-07 23:53:11] main.ERROR: Unable to send mail. [] []

When a product is ordered no confirmation Email is being sent. However it is possible to send invoice emails + pdf. The Problem ist that other emails are not being sent.
How can this be fixed?

Hi,

You need to provide a Magento version and extension version to be able to asses you issue.
