Azure CLI command from "Setting up Entra" Exercise fails to return a value

Question

I copied the Azure (Bash) CLI command from Step 5. in the "Setting up Entra" Exercise, which is required for Step 2, but it fails to return a value. The command is:

DOMAIN_NAME=$(az rest --method GET --url 'https://management.azure.com/tenants?api-version=2020-01-01' --query "value[0].defaultDomain" -o tsv)

Can someone help me understand why it's failing and how to fix it?

Answer 1

The command you shared is supposed to query the Azure API for the default domain name of your tenant and store it in the DOMAIN_NAME variable. If it fails to return a value, there could be several reasons. Here are some common troubleshooting steps:

1. Ensure you are logged in: Make sure you are logged into your Azure account using the Azure CLI. You can log in using:

      
      az login
   

2. Check the command for errors: Sometimes, there might be a minor syntax error or issue with the query. Try running the command directly without storing it in a variable to see if it returns any output:

      
      az rest --method GET --url 
   

   Verify your permissions: Ensure that your Azure account has the necessary permissions to access tenant information. Check the API version: The API version specified might be outdated or incorrect. Ensure that the API version you are using is supported. As of my last update, the provided API version should be correct, but you might want to verify if there are any updates or changes.
3. Debugging the output: If the command doesn't return the expected value, you can remove the --query part to see the full output and debug further

      az rest --method GET --url 
   

If the command runs successfully and returns the expected value, you can then use it in the variable assignment:

DOMAIN_NAME=$(az rest --method GET --url
