Answer 1

The error message "The content for this response was already consumed" typically indicates that there is an issue with the deployment process, possibly related to the ARM template or the Azure CLI command being used. Here are a few steps you can take to troubleshoot this issue:

1. Check the Template: Ensure that your ARM template is correctly formatted and adheres to the required schema. In your provided template, the structure looks correct, but verify that the storage account name is unique and follows the naming conventions (between 3 and 24 characters, using only lowercase letters and numbers).
2. Deployment Name: Make sure that the deployment name you are using (add-storage) is unique within the resource group. If a deployment with the same name already exists, it may cause conflicts.
3. Verbose Logging: Use the --verbose or --debug flags with your command to get more detailed output about what might be going wrong. This can provide insights into any specific issues during the deployment.
4. Resource Group: Confirm that the resource group you are targeting exists and is correctly specified in your command. You can list your resource groups using az group list.
5. Azure CLI Version: Your Azure CLI is up-to-date, which is good. However, if the issue persists, consider reinstalling or updating the Azure CLI to ensure there are no underlying issues.
6. Check Azure Status: Sometimes, Azure services may experience outages or issues. Check the Azure status page to see if there are any ongoing issues that might affect your deployment.

If you continue to face issues, consider simplifying your template to a minimal version and gradually adding complexity back to identify the source of the problem.
