Error when using HistoricalPricing.get_events with open_desktop_session

in Eikon Data APIs

Hello,

I get the below error when using the below code. The same code works well with open_platform_session.

Error:

'{"code":401,"message":"An empty location header is received while retrieving RDP access token","statusMessage":"Unauthorized"}'

This is my code:

import os
import refinitiv.dataplatform as rdp
app_key = os.environ['REFINITIV_APP_KEY']
rdp.open_desktop_session(app_key)
response = rdp.HistoricalPricing.get_events('VOD.L')
print(response.data.df)

    Hello @s397432 and all,

    Conveying the resolution from the relevant support case;

    "

    As per checking and confirmation with our Entitlements Team, your account does not include the RDP Package, hence, you have no access or permission. To request entitlement or add RDP Package in your account, please engage with your Account Manager ... "

    Hello @s397432 ,

    I have tested the following:

    import os
    import refinitiv.dataplatform as rdp
    app_key = 'myValidAPPKey'
    rdp.open_desktop_session(app_key)
    response = rdp.HistoricalPricing.get_events('VOD.L')
    print(response.data.df)

    Getting back the valid result, therefore, do not believe there is an issue with your code.

    I would like to suggest, to re-test the same code with the latest RDP library, by upgrading it to the latest on your test python environment:

    python -m pip install refinitiv-dataplatform --upgrade

    as this looks like one of the issues, known in one of the older releases, and then fixed by the next RDP library release.

    You may also wish, to take the opportunity to test with the next generation of RDP API Libraries: Refinitiv Data Library

    Upgrading has not changed anything, issue is still ongoing

    Hi @s397432

    Can you please advise what if anything the following returns

    display(response.status)

    and possibly

    display(response.data.raw)


  • s397432
    s397432

    response.status => {'http_status_code': 401, 'http_reason': 'Unauthorized'}

    response.data.raw => {'code': 401, 'message': 'An empty location header is received while retrieving RDP access token', 'statusMessage': 'Unauthorized'}

    Hi @s397432

    So, the above indicates that your Eikon licence does not seem to include historical data - certainly not for the VOD.L RIC.

    Can you try a typically 'free' RIC such as EUR= - just to see if that works for you?

    Regardless, you should speak to your Refinitiv Account team to discuss your Eikon Licence flavour.

    ADD: Have any RDP type calls to a Desktop session worked for you? I am not an Eikon licensing expert, but my understanding is that certain Eikon Licences do not allow any API access?

    I have the same error with EUR=

    Moreover, this function works very well with open_platform_session using the above 2 RICs. Is really a licensing issue or a technical issue ?

    streaming data works using Desktop session

    hi @s397432

    The data/content licenced for you MachineId etc used for a platform session can well differ to the content licenced for the Eikon product.

    I can access the above data using both desktop session and platform session - however, I also occasionally find some data/content that I can access with Desktop but not with Platform and vice-versa.

    One thing I forgot to ask - what version of the RDP library are you using - in case it is an older buggy one?

    I am using 

    rdp.__version__
    1.0.0a13

    See PyPi for the latest version

    I am using the same version as you, you can see in my previous reply that I have just upgraded.

    Hi @s397432

    Thanks for confirming. In which case, please reach out to your Refinitiv Account team - so they can check your historical data API access in Eikon/Workspace.

    Please hang fire - a colleague has suggested this could be an API Proxy issue? Will update soon. Thanks

    Hi @s397432

    Are you connecting via a company VPN? If so, can you confirm it works without a VPN?

    As mentioned earlier, this does appear to be an Eikon API Proxy issue and the Proxy team are still investigating...
