Describe the question I am trying to get the list of components being deployed during a deployment using new_list_components.

For that, I am running a bootstrap script and trying to get the list of components deployed. Here is my function. It times out.

def list_components():
    """List components from g   reengrass deployment."""
    ipc_client: GreengrassCoreIPCClient = awsiot.greengrasscoreipc.connect()
    request = ListComponentsRequest()
    operation: ListComponentsOperation = ipc_client.new_list_components()
    operation.activate(request)
    futureResponse = operation.get_response()
    response = futureResponse.result(30)  # seconds

    return response.value

I am not sure what I am doing wrong. Link to the documentation

Can you try increasing the timeout to more than the default to 10 seconds. You can do this when calling

awsiot.greengrasscoreipc.connect(*, ipc_socket=None, authtoken=None, lifecycle_handler=None, timeout=10.0)

@jmklix Thanks for the prompt answer. I just tried, it didn't change anything. The timeout comes from the request:

How do you have your bootstrap script setup to run?

[Minipada]

the component, in the start part was just using python my_script.py

[jmklix]

ListComponentsOperation is only usable by the CLI component and will always throw an unauthorized error. The available API functions that you can use will be documented here.
