Error log in redis-ha inside GKE cluster

[nikhildobriyal]

In my GKE cluster, I installed the application redis-ha with Cloud monitoring metrics enabled for it, it is giving me error 

: "Error while sending request to Stackdriver googleapi: Error 403: Permission monitoring.timeSeries.create denied (or the resource may not exist)., forbidden"

My node's service account has the Monitoring Metric Writer role and Monitoring API is also enabled in the required project.

What am I missing here, can anyone guide me here
