Can't get GetDeviceProfileRequest() working in Python

1

Hi,

I’m trying to us chirpstack_api and GetDeviceProfileRequest() to get DeviceProfile protobuf result.

Here is my code.

import grpc
from chirpstack_api import api

# Configuration.

# This must point to the API interface.
server = "localhost:8080"

# The API token (retrieved using the web-interface).
api_token = "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJhdWQiOiJjaGlycHN0YWNrIiwiaXNzIjoiY2hpcnBzdGFjayIsInN1YiI6IjcwY2QwN2M4LWQ0MGMtNDRhZi1hMWFiLTc0NDk1MmIxOGMyMSIsInR5cCI6ImtleSJ9.nhaZVaqWAHpUDNIYqNiaA2TMYD9apwBmK-E-gVkb_Sc"

device_profile_id = "63f44437-34bd-44a7-9b5d-25dbb9915521"

if __name__ == "__main__":
  # Connect without using TLS.
  channel = grpc.insecure_channel(server)

  # Device-queue API client.
  client = api.DeviceServiceStub(channel)

  # Define the API key meta-data.
  auth_token = [("authorization", "Bearer %s" % api_token)]

  # Construct request.
  req = api.GetDeviceProfileRequest()
  req.id = device_profile_id
  resp = client.Get(req, metadata=auth_token)

  # Print the response
  print(resp)

And here is the error I’m getting.

Traceback (most recent call last):
  File "/home/user/code/DeviceProfile.py", line 30, in <module>
    resp = client.Get(req, metadata=auth_token)

I did test this with Postman and it worked?
