I am trying to run basicdiscovery.py from my windows machine, my green grass core is installed within Raspberry, and i have attached 2 devices to the green grass group.

when i run the basicdiscovery.py with thingName HelloWorld_publisher, I get the following error.

AWSIoTPythonSDK.exception.AWSIoTExceptions.DiscoveryDataNotFoundException

Python version in windows is 3.7.1

Most likely, this is an authorization issue. Services will often return a 404, not because the resource doesn't exist but because you are not authorized to access the resource. Can you verify the policy your credentials are using?

@JonathanHenson :

Same issue here, and policy as follows:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "iot:Publish",
        "iot:Subscribe",
        "iot:Connect",
        "iot:Receive"
      ],
      "Resource": [
        "*"
      ]
    },
    {
      "Effect": "Allow",
      "Action": [
        "greengrass:*"
      ],
      "Resource": [
        "*"
      ]
    }
  ]
}

I solved this one by To manually enter the endpoint section in https://docs.aws.amazon.com/en_us/greengrass/latest/developerguide/test-comms.html?shortFooter=true#corp-network-manual-detection since I am on corporate network.
