hi, I have a k8s ray cluster and it works fine in ray 1.13.0. However, after I upgrade it to ray 2.0.1, I got below error when the operator pod was starting …

 ![image](https://us1.discourse-cdn.com/flex020/uploads/ray/original/2X/6/65d64b1b35c71117ff27a7931e0d867c5e711bc7.png)

For both 1.13.0 and 2.0.1, I use “the same” deploy yaml (the only difference is the image version).

Any help would be appreciated.

Thanks,
