i used the get (temporarypath) to save a layout as pdf to send to its recipient, however started to get the attached error message 

it then skips this script step and creates mthe email with the attachment.
 

Any idea why this is happening and how i could rectify it?

 

 

Show us your script, please.

You need to refactor your variable $path the contents appears to be commented out with "/*"  perhaps you copied and pasted the value in from another source and the needed fields are referenced so the entire contents is wrapped in the /*content*/  which is essentially setting it to nothing.

Also make sure you append the filename and extension for the file.
