Catching ERROR while using ek.set_app_key() function in Python

Oussama · July 2022

Hello everyone, I'd like to catch the error displayed by the function ek.set_app_key() when I pass a wrong key.

Can you please help me to do so using Python. I want to raise an error when the app key is wrong. I tried Try and Except but it seems that the message diplayed by ek.set_app_key() is not recognized as an error by python.

Thank you for your help.

Hi @Oussama

I just heard back from another Eikon API developer who advised the following solution:

ek = rd.eikon
ek.set_app_key("junk")
if rd.session.get_default().open_state == rd.OpenState.Opened:
    print("Opened")
else:
    print("Failed")

Apologies for the misinformation earlier.

Hi @Oussama

I have been advised by the Eikon Data API team that this is not possible.

One option could be to call get_data with a try-except - just after the set_app_key call to see if the set_app_key worked?

The other possible option is to use the newer RD Library for Python with a Desktop Connection.
Once you call open_session, you can then check the session state e.g.

rd.open_session('desktop.workspace')
rd.session.get_default().open_state

OR

desktop_session = rd.open_session('desktop.workspace')
desktop_session.open_state

You can find out more about the RD Library @ - Refinitiv Data Library for Python | Refinitiv Developers
