Hi Cory,
It sounds like you may have some differences between your prod and dev environments that might not be allowing this to work. This might take some troubleshooting to determine the differences between your environments if it's working in dev and not working in prod. My suggestion would be to look at the last date your dev environment was cloned from your prod environment and check which enhancements were submitted between that date and now. One of those enhancements must be negatively impacting your ability to push this enhancement into prod.
If you can't identify the cause of the issue, I'd suggest requesting assistance from ServiceNow Support via HI or phone.
Britt
