Issue Type?

Bug

Module Name

avm/res/network/public-ip-address

(Optional) Module Version

0.7.1

Description

It seems that within the Module for the Public Ip Address there is a false positive.

When using the module the documentation mentions that ddosSettings is 'Optional'.

However when using the module and not providing it it results in an error that the ddosSetting is not present.

When placing a blank 'ddosSetting' property the validator complains that it has missing properties.

(Optional) Correlation Id

No response

Hi @kevin-381ecc2e.

Are you sure your not passing this with empty param. The last time this module published the tests ran and the results are here: https://github.com/Azure/bicep-registry-modules/actions/runs/12813357049/job/35728188982

In which the default test runs with only these inputs:

bicep-registry-modules/avm/res/network/public-ip-address/tests/e2e/defaults/main.test.bicep

Lines 38 to 45 in 86ca03b

	module testDeployment '../../../main.bicep' = [
	for iteration in ['init', 'idem']: {
	scope: resourceGroup
	name: '${uniqueString(deployment().name, resourceLocation)}-test-${serviceShort}-${iteration}'
	params: {
	name: '${namePrefix}${serviceShort}001'
	location: resourceLocation
	}

When i don't provide the parameter it complains that its not present. And when i do provide an empty parameter it complains that protectionMode is missing

@kevin-381ecc2e - what bicep version are you using?

@description('Optional. The DDoS protection plan configuration associated with the public IP address.')
param ddosSettings ddosSettingsType?#

The input is nullable. it will only require protectionmode if the param is supplied
