Question

az deployment group create : "The content for this response was already consumed"

Ricky Ng-Adam 30

Followed instructions to create ARM resource on Microsoft Learn resource group.

When modifying the ARM template and re-executing, the command fails with:

$ az deployment group create --name add-storage --template-file azuredeploy2.json

The content for this response was already consumed

content of template:

Hello @Ricky Ng-Adam ,

We request you to verify if the resource group still exists by using this: az group show --name <ResourceGroupName>

Please post a screenshot of the error if the issue persists.

Thank you.

Hi @RNareddy ,

I am also facing the same issue

az group show --name <resource-group-name> does not produce any error

But when deploying the template I am also getting the same error as cli.azure.cli.core.azclierror: The content for this response was already consumed

az_command_data_logger: The content for this response was already consumed

Looking forward to your response please let me know if you want more details

Run it with --debug at the end then look through the stack trace for the error. For me it was "Message: The storage account named learntemplatestorage123 is already taken." Updated it to learntemplatestorage1234 and it work

Replace az deployment group create with az deployment group what-if - doing this will do a mock/test deploy and will output deployment success or error message.

I got this error:

PreflightValidationCheckFailed - Preflight validation failed. Please refer to the details for the specific errors.
StorageAccountAlreadyTaken - The storage account named <storage_account_name> is already taken.

Likewise, I changed name and displayName for storage account resource and ran deploy with what-if until I got a success message.

In my case, when following ARM template sandbox tutorial my name and displayName wasn't unique enough.

This answer helped me arrive at the correct approach to resolve the issue.

Context: I am working az104-lab06, using the lab-provided files to create VMs, vnet, etc., and using the az cli command in my local environment to deploy resources through the command "az deployment group create --resource-group myResGrpName --template-file myTemplFileName --parameters myParamFileName"

Pointers: make sure you created a resource group and use the resource group name; go through the template file and inspect the values provided for the parameters. The template I used (that was provided) had a parameter named 'adminPassword' whose value was 'null' and that azure did not like. I changed 'null' to a string of my choosing. Likewise, I changed the names (both the var name and value of the vars) of the vms, nics, and nsg to something of my choosing. Lastly, I updated the parameters file to include each of the variables in my template file and gave a value of null to those (value of null only for the parameters file).

As I made changes to my files, I used the command suggested above: az deployment group what-if ................
and made changes accordingly.

Hope this helps.

It may be the resource name is already taken, especially if you are using the one directly in the Learn template. I was able to resolve this by using the --debug flag and seeing that the resource name was already taken. I changed it to include my name to make it unique and it worked.

This issue is now a show stopper for me. I'm using az deployment sub create and I'm unable to refactor the entire IaC template to use group create. We really need a fix here, ASAP. I'm totally unable to push my code.

On a side note, I'm able to generate the ARM JSON using az bicep build, but it still fails when I deploy.

When I was following the Az 104 certification and carried out blank deployment I also faced the same error.

I realized that I had set the default resource group which didn't exist in my Subscription.

az configure --defaults group="az104sbrg"

Once I set the default group to existing RG the issue is resolved.

az configure --defaults group="az104rg"

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:

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).
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.
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.
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.
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.
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.
