Observed message

Code=RequestDisallowedByPolicy

Why it happens

  • The deployment attempts to create or modify resources in a way that violates Azure Policy.
  • A policy requires specific tags, SKUs, regions, or configurations that are missing.
  • The deployment uses a resource type or property denied by policy.

How to fix it

  1. Review the policy details in the deployment error response.
  2. Update the deployment to meet the required policy conditions.
  3. If appropriate, work with an administrator to adjust or exempt the policy.
