Debug Output/Panic Output

No changes. Your infrastructure matches the configuration.

Terraform has compared your real infrastructure against your configuration and found no differences,
so no changes are needed.

Expected Behaviour

Expecting component value of path_only to change the rewrite rule to URL Path

Actual Behaviour

component value of path_only has no impact on the setting.

Steps to Reproduce

1. terraform apply
2. Check the resulting setting in Azure portal
3. Remove component property
4. terraform apply
5. Check the resulting setting in Azure portal. Notice how the setting hasn't changed.
