Thank you for contacting us via the Microsoft Q&A forum.
From your query, it appears you are encountering difficulty reproducing the exercise "Analyzing the limitations of a polling-based web app."
We acknowledge that steps 1 to 5 in the 'Create Azure resources' section were executed successfully as per your screenshots. However, in step 6, it is crucial to replace the placeholder "<YOUR-SUBSCRIPTION-NAME>" with your Azure portal subscription name enclosed in double quotes.
The screenshots indicate your Azure subscription name is "my-subscription." The command displayed in your query shows "<YOUR-SUBSCRIPTION-NAME>" as "here-my-subscription," which differs from the Azure portal name. This discrepancy likely prevents the expected output.
Please replace "<YOUR-SUBSCRIPTION-NAME>" with "my-subscription," exactly as shown in your Azure portal, and retry executing the command.
We have successfully executed the commands using our Azure subscription without encountering any errors, as evidenced in the attached screenshots for your reference: If you continue to experience issues, please inform us in the comments section. We are committed to assisting you further.
