KeyError: headers

Hi there,

I am trying to pull revenue segment data of companies based on a list of RIC codes. And get the keyerror: "headers".

My code looks as follows:

#Making list of instrument codes

riclist_HIP = data_2.Instrument.to_list()

#Calling the data

data_3,err = ek.get_data(riclist_HIP, ['TR.BGS.GeoTotalRevenue.segmentName', 'TR.BGS.GeoTotalRevenue','TR.CompanyName'])

data_3

Error: 

---------------------------------------------------------------------------
KeyError                                  Traceback (most recent call last)
<ipython-input-17-b29cf30df8f5> in <module>
      1 #Making TR API Call
----> 2 data_3,err = ek.get_data(riclist_HIP, ['TR.BGS.GeoTotalRevenue.segmentName', 'TR.BGS.GeoTotalRevenue','TR.CompanyName'])
      3 data_3

~/opt/anaconda3/lib/python3.7/site-packages/eikon/data_grid.py in get_data(instruments, fields, parameters, field_name, raw_output, debug)
    195         return result
    196 
--> 197     return get_data_frame(result, field_name)
    198 
    199 

~/opt/anaconda3/lib/python3.7/site-packages/eikon/data_grid.py in get_data_frame(data_dict, field_name)
    244         headers = [header.get('field', header.get('displayName')) for header in data_dict['headers'][0]]
    245     else:
--> 246         headers = [header['displayName'] for header in data_dict['headers'][0]]
    247     data = pd.np.array([[get_data_value(value) for value in row] for row in data_dict['data']])
    248     if len(data):

KeyError: 'headers'

Could you please assist?

I saw other people have posted around this error but was unclear on how to adapt the solutions proposed to my case.

Many thanks in advance

The issue was that the RIC list I was trying to call was too long for the Eikon API to handle.

I divided the list into chunks and used a for loop to iterate over the chunks of the list.


See example below:

#Making chunks of the list of RICs in order for the API call to process it

chunklist = chunk(riclist, 100)

chunklist

#Using a for loop to get the data based on the chunks of RIC list

content_df = []

for subs in chunklist:

RICs = ek.get_symbology(subs, from_symbol_type='ISIN', to_symbol_type= 'RIC')

content_df.append(RICs)

content_df = pd.concat(content_df)

Hi @Erik77

Please provide what API version you are using? (you can print out ek.__version__)

Please provide sample riclist_HiP (what RICs you used?)

@Erik77

Thank you for providing the details. I'm afraid I do not reproduce the issue you describe.On my end the get_data call using the exact set of RICs and fields that you used returns the data as expected. Are you able to reproduce the issue consistently on your end? Is there any pattern to the problem you may have noticed?

Hi @Alex Putkov. Thanks for looking into it on your end. I found the solution.
