Sandbox deployment fails when configuring resource Microsoft.EventHub/namespaces/eventhubs/providers/roleAssignments

[fix-healthcare]

Followed the steps provided for Sandbox deployment.

Running the powershell script ".\Create-IomtFhirSandboxEnvironment.ps1 -EnvironmentName " generates the following error (most likely occurs only when Azure AD tenant used for app registration is different than tenant tied to your Azure subscription):
New-AzResourceGroupDeployment : 1:00:10 PM - Resource
Microsoft.EventHub/namespaces/eventhubs/providers/roleAssignments
'/normalizeddata/Microsoft.Authorization/3babe616-4482-5441-b294-f0c34074cff7' failed with message '{
