API Request: Error code 1422 | Can not process metadata for request: DataGrid_StandardAsync.reque...

...sts.instruments - non-empty is required

I reran the following code I had successfully run before, but the error appeared this time.

Code:

Complete_Data, err = ek.get_data(List_RIC_Arr,

['TR.RetireDate','TR.ClosePrice.date','TR.ClosePrice','TR.CompanyMarketCap',

'TR.Volume','TR.TtlCmnSharesOut','TR.NumberOfAnalysts','TR.EPSNumberofEstimates',

'TR.EPSNumIncEstimates'],

{'Scale': 6, 'SDate': '2016-01-01', 'EDate': '2016-01-31', 'FRQ': 'D', 'Curn': 'AUD'})

List_RIC_Arr is a list of all RIC for ASX-listed companies.

I am wondering what is going on, and how should I handle this?

Yeah. I think I figured out what is going on. EQSRCH updated the screening output, which includes three empty cells in between, and this cause the data pull issue.

Hi @yiyezhou

Please restart your pc and Eikon Desktop application.

Then try again.

I can successfully retrieve the data (I repeated it for 10 times)

Hello @yiyezhou

Could you please also share the error message/exception that you encountered?

I did restarted everything today, but the problem still exists. My list is all of the ever listed ASX- listed companies, so there are 2612 companies in the list. I am wondering is it because Eikon updated the screen in EQSRCH function, which somehow cause the data pulling issue. I pulled the list by using the code List, err = ek.get_data("lists('ASX-Listed Company List')",["TR.RIC","TR.RetireDate"]).

Yes. Below is the major piece of the error message:

    188 --> 189     result = eikon.json_requests.send_json_request(_endpoint, payload, debug=debug)
    190     191     if result.get('responses'):

Hi @yiyezhou

I do not have the same list as you.

Anyway, please try to reduce the number of RIC lists in a single API call.

Please refer to https://developers.refinitiv.com/eikon-apis/eikon-data-api/docs?content=49692&type=documentation_item

The return datapoint should not exceed 10000 datapoints.

small_list = List_RIC_Arr[0:200]

Please split the list into a smaller list and try again.

Yeah. I think I figured out what is going on. EQSRCH updated the screening output, which includes three empty cells in between, and this cause the data pull issue.
