Opening of Data stream does not work anymore

Hi @adrien.weihs

Can you expand on what you mean when you say:

• After a few trials of opening and closing the price stream (which by the way did not return anything...) - if it did not return anything how did you confirm the open/close was working?
• opening/closing of the stream does not work anymore at all - please expand how this differs from the earlier statement.

you can also try and set the log level e.g.

import logging.config
....
....
ek.set_log_level(logging.DEBUG)
ek.set_app_key('your app key')

and share the output (after removing the application ID, access token etc)

Hi @adrien.weihs

I saw a reply which stated that it was working for some instruments and not others. However, the post is not appearing on here. So, I am guessing it is more a case of it works sometimes and not others regardless of the instrument - is this correct?

I can see from the log output that there is a disconnect occuring between the library and the Eikon instance. It would appear that the internal Websocket server on the Eikon instance disconnected your python app. Can you confirm if Eikon is working and running correctly?

Also, just to be sure that you uninstalled any previous version of the Eikon python library before installed the EAP 1.1.2b0 in PyPi version?

Hi,

Could you share all the script you are running without any personal Id and pwd, then it'll be easier to analyze and understand what is your issue.

Thanks for the script.

I run it with both eikon 1.1.2b0 and 1.1.2b1 version, and I don't reproduce your issue:

I suspect your Eikon product wasn't upgrade to the right version OR you loose credentials to use Eikon API.
That'll explain following trace:

I don't see obvious root cause to your issue.

Let me suggest to clean your Python site-packages directory by deleting manually all subdirectories starting with eikon (sometimes, there is mismatch between different previous versions)
