Was trying to update Policy for KPI-MS using sidecar Istanbul Release.

Updated the following in the values.yaml
dcaePolicySyncImage: onap/org.onap.dcaegen2.deployments.dcae-services-policy-sync:1.0.1
policies:
policyID: |
'["com.Config_KPIMS_CONFIG_POLICY"]'

Getting the following issue:

[2022-03-16 17:16:24,554][INFO ]Starting policy update process...
