broke my pipelines

Thank you,fevinsetter, for your question,

According to this error message, the resource type "Microsoft.Web/Sites" with the name "MyAppName" could not be found in your Azure account. This could be due to a variety of factors, including:

• The resource is unavailable: Check to see if the resource has been added to your Azure account.
• Incorrect resource name: Make sure the name specified in the deployment script corresponds to the resource's name in your Azure account.
• Incorrect subscription: Ensure that the correct subscription is selected in the Azure CLI or Azure PowerShell session.

For more information, see the following articles:

• Azure CLI documentation is available at https://docs.microsoft.com/en-us/cli/azure/webapp?view=azure-cli-latest#az-webapp-create.
• Azure PowerShell documentation can be found at https://docs.microsoft.com/en-us/powershell/module/az.webapp/?view=azps-3.0.

Because you have provided limited information for me to respond to, my response is general. If you are comfortable, we could look into the matter further. Could you please provide more information about the following items:

1. Subscription details for Azure: Confirm their subscription and the name of the resource group that contains the resource.
2. Details on the deployment script: Request the exact script, including the resource type, name, and any parameters.
3. If possible, request access to their Azure portal to determine whether the resource exists, and whether any related error messages exist.
4. Recent changes: Determine whether any recent changes to the resource or environment, such as updates or configuration changes, may have contributed to the problem.
