Role Definition - InputFile Error

Description

When using the New-AzRoleDefinition cmdlet, I'm unable to provide a Role Definition (.json) via the -InputFile parameter, every time it throws an error. The error doesn't indicate if it's an issue with the Cmdlet itself or with the JSON structure.

Error: Object reference not set to an instance of an object.

Steps to reproduce

New-AzRoleDefinition -InputFile "./definition.json"
