What you experienced is an application crash in one of Eikon processes. This is a machine specific issue and a low level error. If it only happened once or twice, it's not worth trying to address it. If the issue is reproduced consistently, you may be able to address it by clearing Eikon cache and/or uninstalling and reinstalling Eikon. If the issue persists after you tried clearing Eikon cache and reinstalling Eikon, you need to report it to Refinitiv Helpdesk. Analyzing the issue to establish the root cause would require generating memory dump for the crash. The Helpdesk can assist you in creating the memory dump and they can analyze it in an attempt to determine the root cause and/or a way to fix the problem.

Hi @yuyang

Are you using Eikon Side-by-Side Integration API or Eikon Data APIs ?

Please share the your code(API calls) so I can try to replicate the issue ?

Thanks.

I used the following code:

case:

import eikon as ek

ek.set_app_key（ '**************************************'）

data = ek.get_data（instrument_list，['TR.IMPLIEDVOLATILITYOFASKPRICE.Date'，'TR.IMPLIEDVOLATILITYOFASKPRICE']，{'SDate'：' - 1M'，'EDate'：'0D'}）[0]

Hi @yuyang

Please try to restart your computer, run the Eikon Desktop application and make sure that it is running properly.

Then try the API again.

If the issues still happen please follow this post to trouble the connection problem.
