Http binding not pulling from Raumserver

Hi OpenHab Community,

I’m currently struggeling a bit with the http-Binding (version 1.14.0) to get a proper response from my raumserver (hosted on the same rasperry pi)

My setup
RaspberryPi 4 2GB Memory
Kernel: Linux 5.4.51-v7l+
OpenHab Version: 2.5.8-1
http-Binding: Version 1.14.0
JSONPath Transformation: Version 2.5.8
Raumfeld Server (Node Version)

The most recent change that was executed was the update to OpenHab 2.5.8-1.
Before the Update everything was fine.
Since then I get the following details in the events.log file:

> 2020-09-18 08:38:10.348 [ERROR] [b.core.service.AbstractActiveService] - Error while executing background thread HTTP Refresh Service
> java.lang.NullPointerException: null
> 	at org.openhab.transform.jsonpath.internal.JSonPathTransformationService.flattenList( ~[?:?]
> 	at org.openhab.transform.jsonpath.internal.JSonPathTransformationService.transform( ~[?:?]
> 	at org.openhab.core.transform.TransformationHelper$TransformationServiceDelegate.transform( ~[bundleFile:?]
> 	at org.openhab.binding.http.internal.HttpBinding.execute( ~[?:?]
> 	at org.openhab.core.binding.AbstractActiveBinding$BindingActiveService.execute( ~[bundleFile:?]
> 	at org.openhab.core.service.AbstractActiveService$ [bundleFile:?]

Execution of Play or Stop commands via Raumfeld Server is fine.

Also I get the proper JSON Details when I go to the HTTP URL of the Raumserver.

http Binding config:


Openhab has been redirected on Port 8081 and is working fine on this way

Did also a troubleshooting by uninstalling the http binding. Log went silent.

After reinstalling of http binding (even without) details the issues above started again to fill the log.

Thanks for any help on this topic.

for whatever reason the issue solved by itself this morning.
This one can be closed
