Xporter create attachment and send Custom Mail doesn't work Edited

[Laith Ata]

Hi,

I'm using ScriptRunner and Xporter to create document in one postfunction und in another send a custom Mail. However after the Jira Core upgrade from 7.13 to 8.8.1 Xporter create the document but the costum mail can't add the attachment. I tried the whole process without xporter it worked as expected.
