So I have an odd issue with GKE cluster stuck in a updating status In rancher it shows

This cluster is currently Updating.

Googleapi: Error 400: Master version "1.20.12-gke.1500" is unsupporte" is unsupported., badRequest

Looks like Google updated it to a supported version

v1.21.14-gke.2700

already but I am unable to update the version in rancher. Tried to update it via terraform but I am just getting the error

Error: [ERROR] waiting for cluster (c-cx868) to be updated: timeout while waiting for state to become 'active, provisioning, pending' (last state: 'updating', timeout: 30m0s)

Not sure how to clear the status and to stop rancher trying to downgrade the cluster. Anyone seen this before?
