While using the regular haystack-rt.jar module on an existing Tridium Niagara 4.15 station, I have attempted to install nhaystack to make use of the REST API integration
After copying the nhaystack-rt.jar and nhaystack-wb.jar into my modules, the station no longer loads
The README mentions using a patched version of haystack-rt.jar, but I cannot find any documentation of where to download that, so I'm looking to see what I might be missing in integrating nhaystack into my station
