Enable logging by category group for microsoft.network/networkmanagers/ipampools to Log Analytics - "code": "ResourceNotFound"

[feliasson]

Details of the scenario you tried and the problem that is occurring

I encountered an issue with the built-in Azure Policy initiative (Enable allLogs category group resource logging for supported resources to Log Analytics) that deploys diagnostic settings for resources of type microsoft.network/networkmanagers/ipampools.

The policy definition in your repository:
https://github.com/Azure/azure-policy/blob/master/built-in-policies/policyDefinitions/Monitoring/DS_LA_network-networkmanagers-ipampools_DINE.json

Despite the policy being applied correctly, deployments are failing with the below provided error.

• The exact IPAM pool resource ID(s) exists and is within the policy assigned scope
• All other resource types within the policy initiative are successfully deploying diagnostic settings from the same policy assignment
• The IPAM pools shows up as "Resources to Remediate"
  • The remediation task however only triggers through manually clicking Remediate in the portal
    • Once triggered, the deployment fails with the below error.
