Deploy the ARM template to the newly created Azure Resource Group

Question

Hello, I'm new to Azure Digital Twins,

I'm learning course "Connect IoT data to mixed reality with Azure Digital Twin and Unity", I follow every step but come to this step "Deploy the ARM template to the newly created Azure Resource Group" I got error:

ERROR: {"code": "InvalidTemplate", "message": "Deployment template validation failed: 'The template resource '' of type 'Microsoft.Authorization/roleAssignments' at line '344' and column '5' is not valid. The name property cannot be null or empty. Please see https://aka.ms/arm-template/#resources for usage details.'.", "additionalInfo": [{"type": "TemplateViolation", "info": {"lineNumber": 344, "linePosition": 5, "path": "properties.template.resources[17]"}}]}

Hello @An Nguyen Thuan ,

When I followed the instructions in ARM-Template README on github, the objectId and userId were zero. I changed the queries to

$objectid=$(az ad sp list --display-name ${appreg} --query [0].id --output tsv)  
$userid=$(az ad signed-in-user show --query id -o tsv)  

When I first start the deployment as described in ARM-Template - Step 6 deploy, I got the same error as you. It is important that the parameters are set. So, check if userId and objectId are set correctly.
