Hi, I am trying to run flink with the flink kubernetes operator using my own docker image, However, it is unable to start the flink cluster with the null pointer exception:

2023-09-30 00:04:01,950 ERROR org.apache.flink.runtime.entrypoint.ClusterEntrypoint        [] - Could not create application program.
java.lang.NullPointerException: null

In my docker image, I get flink on /shared/flink/ but I did configured ENV for both PATH and FLINK_HOME to the correct location. Does anyone know what would trigger this NullPointerException? Thanks

Can u pls check if u have packaged ur jar file correctly?

The problem is solved, I set a different FLINK_HOME which is different from the one that is mount by the flink operator.
