#387 adding NHaystackServer breaks the nHaystack service

tony cole Mon 2 May 2016

Running 3.8.38 AX Supervisor with nhaystack 1.2.5, the nHaystack service was functioning fine until adding nHaystackNetwork with a nHaystackServer. The nHaystackServer was configured and works great except it breaks the NHaystack service. Based on information found, it says these should co-exist? Any idea why this is not working?

Error connecting from browser after installing the nHaystackServer: url: ip:port/haystack/read?filter=point

Error: ver:"2.0" dis:"java.lang.NullPointerException" errTrace:"java.lang.NullPointerException\n" err empty

To get the service functioning again, I have to delete the nHaystackNetwork and then action/rebuild cache, if I try to just rebuild the cache without deleting the network, it generates a nullPointerException and does not work.

Hi Tony,

Do you have an error message from the Niagara Platform Application Director?

Any other information that could help?

Personally I never ran 3.8.38, we skipped that and went straight to 3.8.41 which seems ok.

Regards, Richard
