Stephen,
Wmusers are there to share and help you in right direction…
The above Exception shows that EDI document is not valid and not being recognized by TN.Reason might be the Envelope data (ISA/GS are not valid and formatted properly with mandatory fields).
So before submitting the edidata to TN use the following service that will help validating the EDI Envelopes (wm.b2b.edi:envelopeProcess)located in the WmEDI package.It gives output isValid (true or false) and ErrorArray.
Hope you have installed the corresponding EDI X.12 216 docType in TN.
Please check this thread for more understanding wmEDI process.

Also please check the Documentation located in the filesystem under the packages WmEDI,WmEDIForTN that can answer your above mentioned questions.
HTH.
