Error code 400 | Backend error. 400 Bad Request for 0#SPXW*.U

Thanks Jason, I tried CF_NAME and still getting the same error....

I am still experiencing the issue, but only with certain options chain RICs, which makes me think it maybe it has to do something with the universe size...??

For example ;

ek.get_data(["0#MSFT*.U"],['CF_NAME']) works fine. No errors. , and I can run it again and again and have zero problems. All values are returned as expected.

But when I run ek.get_data(["0#SPXW*.U"],['CF_NAME']) I consistently get "ERROR: pyeikon: Backend error. 400 Bad Request"

Why? this is exactly the same formula, just a different RIC....

The client at UBS is also experiencing the same problem: "

We see these EikonErrors on a different set of names today.

For 0#SPXW*.U and 0#SPY*.U: Error code 400 | Backend error. 400 Bad Request

For 0#AMZN*.U, 0#APH*.U, 0#TSLA*.U: Error code 408 | Request timeout occured"

Where do we escalate this to? clearly something is going on since both client and I are able to observe the same behavior....

Thanks Chavalit, have raise in case 08439430 .

thank you. Interestingly if I change the field i get a slightly different error

ek.get_data('0#SPXW*.U','STRIKE_PRC') . But if i try the same request 10 times it actually works once or twice.... so, there is stability issue somewhere here.

ERROR:pyeikon:Request timeout occured
