StreamingPrices unknown subscription

Hello,

My coworkers and I are facing an issue when we try to execute the StreamingPrices function on a Python local environment.

Here is a typical example of what I am trying to run:




import eikon as ek

import pandas as pd

 

ek.set_app_key('my_api_key')

 

def get_eikon_data(contract, fields):

 

                streaming_prices = ek.StreamingPrices(

                    instruments=[contract],

                    fields=fields)

                streaming_prices.open()

                df = streaming_prices.get_snapshot().rename(columns={"Instrument": "Contract",

                                                                      "CF_TIME": "Timestamp",

                                                                      "ACVOL_1": "Volume"})

        return df

get_eikon_data('CLc1', ["ASK", "BID", "ACVOL_1", "CF_TIME"])

Now, here is the output we get: “Receive status message for unknown subscription id 2”

When running the logs, we get more details as followed:

The only thing I replaced is my API key. Everything else including john doe is from the logs.

Can you please check that out?

Many thanks.

Thank you for reaching out to us.

I can run the code properly.

I could be network or firewall issues. The error indicates that it is unable to connect to the platform.

Please contact the Eikon support team directly to verify what the problem is.
