We have written python code to communicate with google dialog flow. It is working fine on our local machines and in one of the build machines also it is working fine. Below is the code we write to communicate with dialogflow.
def diagflowInteraction(project_id, session_id, texts, language_code):
"""Returns the result of detect intent with texts as inputs.
Using the same `session_id` between requests allows continuation
of the conversation."""
import dialogflow_v2 as dialogflow
os.environ['GOOGLE_APPLICATION_CREDENTIALS'] = '/data/DialogflowConfig.json'
session_client = dialogflow.SessionsClient()
session = session_client.session_path(project_id, session_id)
print('Session path: {}\n'.format(session))
text_input = dialogflow.types.TextInput(text=texts, language_code=language_code)
query_input = dialogflow.types.QueryInput(text=text_input)
print(query_input)
response = session_client.detect_intent(session=session, query_input=query_input)
But one build machine which we are using for production is throwing below error.
google/api_core/timeout.py\", line 214, in func_with_timeout\n return func(*args, **kwargs)\n File \"/home/nodeappuser/.local/lib/python3.5/site-packages/google/api_core/grpc_helpers.py\", line 59, in error_remapped_callable\n six.raise_from(exceptions.from_grpc_error(exc), exc)\n File \"<string>\", line 2, in raise_from\ngoogle.api_core.exceptions.ServiceUnavailable: 503 Getting metadata from plugin failed with error: '_RSAPrivateKey' object has no attribute 'sign'\n","timestamp":"2020-11-16T20:02:16.123Z","type":"err","process_id":0,"app_name":"ChatBotInterface"}
Not sure what is causing this issue on that machine. Couldn't find much on internet related to the issue. We found Error in python cryptography module: _RSAPrivateKey' object has no attribute 'sign for same type of issue which says having old cryptography library (1.7.1) is the issue and suggested to upgrade to 2.6.1. But all our machines has cryptography latest version 2.6.1 including the machine which is having the issue.
cryptography 1.2.3
pycrypto 2.6.1
We have production drop in 2 hours. Can any one please help me to fix this issue.
