Auto Email Custom Report Error

Hi,
I have created a custom sales order report by selecting columns in the report view, and sving it.
I am then trying to set up an auto email message however I get the following error when trying to send it


Not found
Sales Order Item SO-00210 not foundThe resource you are looking for is not available
The resource you are looking for is not available

If you check, on the report itself the SO-00210 appears perfectly fine.

What is happening?
