Mail Helper and file attachments

Permalink January 31, 2020 at 2:07 PM

I see in the mail helper some notes about attaching files to mail. I am using current concrete5 5.7.3 version

$mailHelper->addAttachment(File::getByID(17));
 $attachment->filename = "CustomFilename";

But I get an error:
call_user_func_array() expects parameter 1 to be a valid callback, class 'Concrete\Core\File\Version' does not have a method 'getPath'

I don't know why I see an error about getPath, getByID is getting the file object? Does anyone have a solution? Does the mail helper really send attachments, I'm seeing some conflicting posts in the forums.

thanks
