Kruize VPA demo - failed to generate recommendations for experiment: optimize-sysbench

[chandrams]

When kruize was installed using kruize operator in Kruize vpa demo, VPA optimize-sysbench was not shown on doing a "kubectl describe vpa".

Below error is seen in the kruize pod log.

2025-11-1406:33:21.122 ERROR [pool-2-thread-1][AutoscalerImpl.java(88)]-Failed to generate recommendations for experiment: optimize-sysbench
2025-11-1406:33:21.122 ERROR [pool-2-thread-1][AutoscalerService.java(67)]-Cannot invoke "com.autotune.analyzer.kruizeObject.KruizeObject.getDefaultUpdater()" because "kruizeObject" is null

In non-operator mode, optimize-sysbench VPA was created.

[shreyabiradar07]

As per the documentation Kruize will create VPA object automatically once experiment is created succesfully.

However vpa object is not getting created via the Operator mode of Kruize deployment (./vpa_demo.sh -c openshift -i quay.io/kruize/autotune_operator:0.7.1)
