System configuration:
Hardware: Raspberry Pi5
Openhabian and OH 5.2.1
Persistence services: InfluxDB 1.12.4 (default), rrdj4 (few temporary stuff)
Current Behavior
When using the rest endpoint like this:
http://openhabian:8080/rest/persistence/items/EM_ForecastCorrection?time=2026-08-10T10%3A56%3A00.000Z&state=1.0
The API returns Error 500:
"{\\"error\\":{\\"http-code\\":500,\\"exception\\":{\\"class\\":\\"java.lang.NullPointerException\\"}}}"
The same happens in JavaScript rules:
items.EM_ForecastCorrection.persistence.persist()
results in the above exception
Same for DSL rules:
EM_ForecastCorrection.persist()
A call to EM_ForecastCorrection.persist("rrdj4") works! EM_ForecastCorrection.persist("influxdb") doesn't.
Items do persist correctly via persistence strategies.
Expected Behavior
API and scripts should be able to presist a value on request and not only rely on persistence strategies.
Both API and scripts worked in OH 5.1.4 up to OH 5.2 M1.
Steps to Reproduce (for Bugs)
Have influxdb 1.12.4 running and set up.
Create a simple script like the one mentioned above.
Investigations so far:
Installed earlier versions and milestones. The issue was introduced between 5.2 M1 and 5.2 M2.
