Azure ARM deployment failed with BadRequest

Code=BadRequest

Azure Resource Manager rejected the deployment request because one or more supplied values do not match what the target resource expects.

BadRequestdeployment

Observed message

Code=BadRequest

Why it happens

  • The deployment contains values that don't match the target resource requirements.
  • An exported template or Bicep file includes invalid or stale properties.
  • A nested property is malformed or incompatible with the selected SKU or region.

How to fix it

  1. Inspect the inner status message to identify the exact property causing the failure.
  2. Compare the deployment payload with the current template reference for that resource type.
  3. Update invalid values and rerun the deployment.
