ConnectTimeout('') while access token renew

v.kuznetsov

Hello. I have some troubles with refinitiv-data python library.

Sometimes in access token renew process I receive ConnectTimeout('') error. The problem is when this happens - main thread does not catch this error. It just receives this message in console:

An error occurred while requesting URL('https://api.refinitiv.com/auth/oauth2/v1/token').
        ConnectTimeout('')
[Error 0 - empty error] empty error description

Library version: 1.0.0b9 (also tried 1.0.0b6 with the same result)

Any solution/advice how to handle this?

Hi @v.kuznetsov

I performed a test where I turn off my WiFi and received the same error as you. To programmatically react to this error, you can apply callbacks as outlined at the bottom of this tutorial source code. That being said, the callbacks only report a description which unfortunately doesn't provide any useful details, i.e. "empty error description". In addition, the session does provide 2 methods (get_last_event_code and get_last_event_message) which do not return anything - perhaps because there is no error description.

As for why the error is occurring, I assume it happens when you attempt to open a session? Does it happen all the time? If so, there may be proxy issues within your environment that is preventing you from accessing the service.
