initializing policymanager failed

Error message

initializing policymanager failed

What it means

Returned by NewBundle when policies.NewManagerImpl fails while building the policy manager from the config's root group. This wraps policy-tree construction failures — e.g. unregistered policy types or malformed policy expressions in the config being loaded.

Solutions

1. Check the wrapped error for the failing policy path/definition
