The instrument issue when I fetch historical PE ratio of SPX constituents

ylian

I use the following statement to fetch historical PE ratios of SPX constituents.

rcc, err=ek.get_data("0#.SPX(2002-08-09)",fields=["TR.RIC","TR.InstrumentDescription", "TR.RIC.date"])

instruments=rcc['RIC'].tolist()

df,err=ek.get_data(instruments, ['TR.PE', ‘TR.PE.date'], {"SDate": "2002-08-09", "EDate":"2002-08-09"})

Below is the message from Spyder.

 File "C:\Users\xxx\Anaconda3\lib\site-packages\eikon\data_grid.py", line 189, in get_data
    result = eikon.json_requests.send_json_request(_endpoint, payload, debug=debug)

  File "C:\Users\xxx\Anaconda3\lib\site-packages\eikon\json_requests.py", line 127, in send_json_request
    _check_server_error(result)

  File "C:\Users\xxx\Anaconda3\lib\site-packages\eikon\json_requests.py", line 203, in _check_server_error
    raise EikonError(int(server_response['ErrorCode']), error_message)

EikonError: Error code 1422 | Can not process metadata for request: DataGrid_StandardAsync.requests.instruments - non-empty is required

(1) I manually create a subset of the "instruments" and run the get_data statement. And it works fine. But when I include the instrument with the 500 RICs, it reports errors.

(2) Some tickers do not return PE ratio, such as TNB.N^E12. Do you have any other alternative get PE ratio for this RIC?

Can you advise? Thank you.

Hi @ylian

1. The instruments variable contains empty value. So it causes the error.
