Fail delivery email does not have a 'body' content

The following is what in the ‘Body’ properties of a fail delivery email. It does not have a ‘body’ content.

Using doc.getFirstItem(“body”) crashes the system.

Using doc.hasitem(“body”) returns true.

How can i resolve or skip processing this type of fail delivery emails ? Thanks
