error : @{message=Internal Server Error while processing this request.; code=5000}

So I'm having an issue adding notification profiles via the REST API. Has anyone else seen this?

https://ValidServer:8060/api/json/discovery/addDeviceToNProfile?apiKey=ValidAPIKey&deviceName=ServerIPAddress&profileName=MarkhamSite&criteria=500000000000000000000000000&performance

Monitors=DiskUtilization,Win-CPUUtilization

I'm not sure how to even troubleshoot this.
