Unable to switch to using kubeip v2, returning region-related error

[MikeW1901]

Running the latest version of KubeIP v2's DaemonSet on GKE, pods start in the correct place but then immediately throw this error:

func: "main.assignAddress"
msg: "failed to assign static public IP address to node (node id)"
error: "check if static public IP is already assigned to instance (node id): failed to list assigned addresses: failed to list available addresses: googleapi: Error 400: Invalid value for field 'region': 'us-central1-a'. Unknown region., invalid"

(It should fail as it's got a static IP - it's currently using Kubeip v1 which we want to upgrade from as it seems to wipe other Kubernetes labels when setting its own - but I'm suspecting this region error is different, as the region presumably should be us-central1? No region is defined in the user-facing KubeIP config so I'm unclear what could need tweaking here).

Any assistance appreciated!

I had the same issue so added an env entry for region myself which seems to have resolved this problem. E.g.

        - name: REGION
          value: "us-central1"
