Workflow task Send PDF

[s2b-git]

Been testing a bit workflows and it appears that Send PDF task doesnt deliver PDF even this PDF is visible in Mails to Send panel.
With one exception, when I click Manual Sending this attachment goes correctly, but when I leave this email for cron, the PDF template is not attached.
The only error I can trace is:
PHP Warning: bcadd(): bcmath function argument is not well-formed in /var/www/html/vendor/yetiforce/yetiforcepdf/lib/Math.php on line 68

Core file mentioned in log was not touched.
Can anyone confirm this please, so I can report bug or dig more?
It is on latest stable

Best

Exactly same situation here

In my instance also not working as expected. Have not been using this sending method as it feels inconsistent. But checked s2b-git scenario and yes it not works. Also YF6.4

The same happens to me,
I try to send a pdf but the mail arrives only without the pdf attached

What would be the solution to this?

Issue also confirmed on my side.
I've noticed that if you attach a PDF file to your email template, it is delivered but it does not offer the same functionnalities as send PDF via workflow.

migrated 6.4 to 6.5 and hit the same. Anyone resolved in the meantime?

In YF version 7.x I don't see this issue occuring.
