Strange Azure Resource Group Deployment Error

Question

As part of my release definition, I have specific a Azure Resource Group Deployment task with action of Create or Update.

When I start a new release, the Azure Resource Group Deployment encounters the following error

2018-11-27T20:52:54.1969890Z ##[error]At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/arm-debug for usage details.

I've reviewed the azure template json and don't see anything relative to this error. There are variables related to the Traffic Manager, see below:

"names-traffic-manager": {
  "type": "string",
  "metadata": {
    "description": "The name of the traffic manager instance"
  }
},

{
  "apiVersion": "2015-11-01",
  "type": "Microsoft.Network/trafficManagerProfiles",
  "name": "TrafficManager",
  "location": "global",
  "properties": {
    "profileStatus": "Enabled",
    "trafficRoutingMethod": "Priority",
    "dnsConfig": {
      "relativeName": "[parameters('names-traffic-manager')]",
      "ttl": 30
    },
    "monitorConfig": {
      "protocol": "HTTPS",
      "port": 443,
      "path": "/"
    }
  }
},

Thanks for input...I've also verified the Traffic Manager profile is correct in Azure Portal

Have you carefully read the error message and attempted to correct the stated cause of the problem, which is Domain name dev-xxxxcu-tm.trafficmanager.net already exists. Please choose a different DNS prefix? — Daniel Mann
I think what is being suggested here is to try a completely different resource domain name for traffic manager as a resource has already taken the name you are using. — Colin B
I understand what the Conflict message means, but am unsure where to correct the issue. There are properties related to traffic manager in the azuredeploy.json file, I've updated the OP with that. — Tango Down

You need to change the traffic manager relativeName, you would do that at this line:

"relativeName": "TrafficManager-unique-name-3245235",

You can also use a parameter to construct the name on the fly:

"relativeName": "[concat(parameters('names-traffic-manager'), '-traffic-manager')]
