@zhanghongtong I had the cluster up and running a few days ago in my bare-metal K8s and I installed it via helm repo only. I took down the cluster to make some changes with my storage and PVs. Now, when I try to install it again, it is throwing me this error.

Note: I am currently able to install emqx cluster by cloning the repo locally and then using the chart from there.

@nitishpt Can you run helm install --namespace iot-pipeline --name emqx -f values-production.yaml emqx/emqx --devel --dry-run --debug and show me the results?

@zhanghongtong Here it is:

@nitishpt I suggest you upgrade to helm3 and retry emqx installation

[nitishpt]

@zhanghongtong Okay. Though I still don't get why this error is being thrown. AFAIK, isn't the EMQX chart using apiVersion as 'v1'?
