Greengrass V2 positioning for new device

Hi, thanks for using Greengrass. If you got the device to install and run correctly without issues the device is provisioned. Did you try making any deployments to the device and see if they work as well? The core device entry in your AWS account will appear when your device first sends a status report to cloud. Status reports are by sent every 24 hours (unless you change this frequency) and after each deployment issued from the cloud (your AWS account's console/AWS CLI/AWS SDK) has been received and finished on the device.

so if I understand the deployment process for gg v2 correctly, I need to have the thingArn. However, as far as i know there is no new thing is created. I wonder what did i do wrong.

here is the config for gg installer

---
services:
  aws.greengrass.Nucleus:
    version: "2.5.3"
  aws.greengrass.FleetProvisioningByClaim:
    configuration:
      rootPath: "/greengrass/v2"
      awsRegion: " <> "
      iotDataEndpoint: "<>.amazonaws.com"
      iotCredentialEndpoint: "<>.amazonaws.com"
      iotRoleAlias: "GreengrassCoreTokenExchangeRoleAlias"
      provisioningTemplate: "test-fleet-template"
      claimCertificatePath: "/greengrass/v2/claim-certs/claim.pem.crt"
      claimCertificatePrivateKeyPath: "/greengrass/v2/claim-certs/claim.private.pem.key"
      rootCaPath: "/greengrass/v2/AmazonRootCA1.pem"
      templateParameters:
        model: "rpi4"
        parking: "false"

I also tried to use the wrong provisioningTempalate, but the installer could still run successfully

I am not sure why i rpi cant connect connect to the backend, the ip match with my device
