Unable to provision IOT Devices using FleetProvisioningByClaim

I am trying to provision a new device using fleetProvisioningByClaim following https://docs.aws.amazon.com/greengrass/v2/developerguide/fleet-provisioning.html, for this i have all my claim credentials on the device and my iotDataEndpoint/iotCredentialEndpoint/provisioningTemplate/rootCaPath are set and on running the final command sudo -E java -Droot="/greengrass/v2 i did received Successfully set up Nucleus as a system service and greengrass is running as well but couldn't find the device on iotCore, and as checked in my greengrass.log, attached logs for the same. Also my nucleus and main.log files are empty. Is there any other way to debug such issue?

config.yaml file

services:
  aws.greengrass.Nucleus:
    version: "2.5.6"
    configuration:
      awsRegion: "us-east-1"
  aws.greengrass.FleetProvisioningByClaim:
    configuration:
      rootPath: /greengrass/v2
      awsRegion: "us-east-1"
      iotDataEndpoint: "$iotDataEndpoint" // replaced with endpoint as retrieved from aws iot describe-endpoint --endpoint-type iot:Data-ATS
      iotCredentialEndpoint: "$iotCredentialEndpoint" // replaced with endpoint as retrieved from aws iot describe-endpoint --endpoint-type iot:CredentialProvider
      iotRoleAlias: "GreengrassV2TokenExchangeRoleAlias"
      provisioningTemplate: "$provisioningTemplate" // Value as copied from `Fleet provisioning templates` in IOT Core
      claimCertificatePath: "/greengrass/v2/claim-certs/claim.pem.crt" // copied from certificatePem as mentioned in https://tiny.amazon.com/n4qhu1jm/docsawsamaziotlateapirAPI_
      claimCertificatePrivateKeyPath: "/greengrass/v2/claim-certs/claim.private.pem.key" // copied from keyPair.privateKey as mentioned in https://tiny.amazon.com/n4qhu1jm/docsawsamaziotlateapirAPI_
      rootCaPath: "/greengrass/v2/AmazonRootCA1.pem" // verified they are present
      templateParameters:
        ThingName: "$thingName" // replaced $thingName with my thing name
        ThingGroupName: "$thingGroupName" // replaced $thingName with my group name

Java command:
