Timeout fetching Google stackdriver monitoring metrics (Client.Timeout exceeded while awaiting headers)

Issue

Stackdriver exporter throws the below error when fetching stack driver monitoring metrics.

{ labels: { compute.googleapis.com/resource_name: "gke-company-resource-name" k8s-pod/app: "prometheus-stackdriver-exporter" k8s-pod/release: "stable" } logName: "projects/company/logs/stderr" receiveTimestamp: "2022-04-20T01:15:51.291425040Z" resource: { labels: { cluster_name: "company-cluster1" container_name: "prometheus-stackdriver-exporter" namespace_name: "internal-services" pod_name: "stable-prometheus-stackdriver-exporter-pod-suffix" project_id: "company-project-id" } type: "k8s_container" } severity: "ERROR" textPayload: "level=error ts=2022-04-20T01:15:49.913Z caller=monitoring_collector.go:185 msg="Error while getting Google Stackdriver Monitoring metrics" err="Get \"https://monitoring.googleapis.com/v3/projects/company-cluster1/metricDescriptors?alt=json&filter=metric.type+%3D+starts_with%28%22compute.googleapis.com%2Finstance%2Fcpu%22%29&prettyPrint=false\": net/http: request canceled (Client.Timeout exceeded while awaiting headers)"" timestamp: "2022-04-20T01:15:49.913872755Z" }

Question

What is the timeout parameter that has to increased to prevent timing out ? Below Helm chart is used to deploy stack driver exporter.

Start in monitoring_collector.go around line 185 and inspect the Helm chart used to deploy the exporter. Trace the Google Cloud Monitoring client timeout configuration and determine which setting controls the request shown in the error. Done means the responsible timeout parameter is identified and its configuration or documentation addresses the reported timeout.
