Couldn't transform value in label / MAP

Today I installed openhab 4 on a fresh openhabian device. Afterwards I restored my openhab 3 configuration.
Now I always get hundreds of warnings like

2023-07-28 22:36:45.841 [WARN ] [s.internal.SingleValueTransformation] - couldn’t transform response because transformationService of type ‘JS’ is unavailable

I already installed several transformation services and restartet openhab but the warnings remain. Any ideas how to fix it?
