volume folder created with unexpected different user and folder

[brightzheng100]

Some volume folders created with an unexpected different user user, which is my current OS login user, which is NOT expected.

$ ls -al /storage/
total 24

I defined my custom config like this -- Note that I tried to tweak the setup script to change the owner explicitly to be root:root but didn't help:

kind: ConfigMap
apiVersion: v1
metadata:
  name: local-path-config
  namespace: local-path-storage

    {
      "nodePathMap":[
        {
          "node":"DEFAULT_PATH_FOR_NON_LISTED_NODES",
          "paths":["/storage"]
        }
      ]
    }
  setup: |-
    #!/bin/sh
    set -eu
    echo mkdir -m 0777 -p "$VOL_DIR"
    mkdir -m 0777 -p "$VOL_DIR"
    echo chown root:root -R "$VOL_DIR"
    chown root:root -R "$VOL_DIR"
    echo chmod 0777 -R "$VOL_DIR"
    chmod 0777 -R "$VOL_DIR"
  teardown: |-
    #!/bin/sh
    set -eu
    rm -rf "$VOL_DIR"
  helperPod.yaml: |-
    apiVersion: v1

      containers:

And the complete logs while creating the volume:
