EikonError: Error code 408 | UDF timeout occured. The operation was canceled.

CodeWave

Hi,

I get the following error while conducting a heavy loop:

The loop I am conducting looks like this:

I dívided the ~12,000 firms to groups of 500 to avoid the limit for 10,000 data points per search since I search with 17 fields/data items. How could I best implement the search to all of the 12,000 firms or fix the error occuring?

Many thanks for any advice!

Hi @CodeWave

You can use try, except code block to handle error.

try:
   df,err = ek.get_data(...)
except ek.EikonError:
   //do something, perhaps retry the request again after some period of time

Hi,

Ok. Thanks! But what is causing the problem so I can prevent the error in the first place? Meanwhile, I will try to make a try-expect structure to handle the issue.

Hi @CodeWave

Have you tried adding a sleep() between each get_data() call?

I am not an expert on the inner workings of the Eikon API, however, the trace you shared mentions server errors around when the json request is sent to the server.

There are a lot of possible factors such as network, service availability on server side, etc...

So implementing try, except code block is safer.

Please also note that there is a 5-requests-per-second limitation as well, (please review the API limitation document at this URL, https://developers.refinitiv.com/eikon-apis/eikon-data-api/docs?content=49692&type=documentation_item

Hi,

Okay. Could you provide a short example or refer to a thread where there is an example provided of such a try-expect structure that works efficiently?

Many thanks.

CodeWave

No, I had not tried. Thanks for the tip! I think i will try using a try-expect structure and also use sleep between each iteration for chunked firm lists. We'll see how that works out.

Hi @CodeWave

The example to catch eikonError is provided, however how to handle it really depends on app developer to handle it in their app logic.

This is an example

gotData = False
while not gotData:
    try:
        df,err = ek.get_data(...)
        gotData = True
    except ek.EikonError:
        time.sleep(3)
