So, I have downloaded and attempted to use the template provided in Genesys Cloud and I keep getting errors regarding the headers. 

I have not changed these at all from the template, and I have just put data around it to test an Import in our development/testy environment.

Any Ideas why I would be receiving this error?  

Thanks!

May want to see if the following post helps - especially Julio's last post about things to check.
