I am trying to deploy a VM with diagnosting settings

Question

During the ARM template deployment, I get this error related to pre-existing Event Hub Name space - Sec-2-eventhub:

The deployment 'Deployment-rg-vms-20220208010117' failed with error(s). Showing 1 out of 1 error(s). Status Message: Can not perform requested operation on nested resource. | Parent resource 'Sec-2-eventhub' not found. (Code:ParentResourceNotFound)

This is my azuredeploy.json

and this is my azuredepy.paramenters.json file

    },
    "adminUsername": {
      "value": "myadmuser"
    },
    "adminPassword": {
      "value": "SomeS3curePassword!"
    },
    "eventHubNameSpace": {
      "value": "Sec-2-eventhub"      
    },
    "diagStorageAccount": {
      "value": "sec2ehdiag01"
    },
    "virtualNetworkRG":  {
      "value": "vnets-rg"
    },
    "virtualNetworkName": {
      "value": "core-net"
    }
  }
}

what could be wrong?
