Hi @wasin.waeosri

There were several issues here

• Corporate firewall/network issues - which were addressed internally by client
• wrong credential values being used e.g. My.Refinitiv login details instead of MachineID
• MachineID was not permissioned for RDP Snapshot API - only RTO - so the client was advised to use streaming interface with the Snapshot option

Hi @Merijn

your code as far as I can read it looks fine. I tried the following and it worked OK

import refinitiv.dataplatform as rdp

print(rdp.__version__)

rdp.open_platform_session(
    APP_KEY, 
    rdp.GrantPassword(
        username = RDP_LOGIN, 
        password = RDP_PASSWORD
    )
)
universe = ['EUR='] 
fields = ['ASK', 'BID']
response = rdp.Pricing.get_snapshot(universe, fields)
print(response.data.df)
rdp.close_session()

can you confirm which version of the RDP library you are using?

I am using v 1.0.0a8.post1 from refinitiv-dataplatform · PyPI

If you are also using the same version, then please enable logging and attach the output - after removing any credentials etc)

import logging
logging.basicConfig(format='%(asctime)s - %(name)s - %(levelname)s - %(message)s', level=logging.DEBUG)

Hi Umer,

Thanks for your quick reply. I ran your code - with logging enabled. I still see the same error.

The version I have installed is 1.0.0a7.post7.

See output from the log created attached.

refinitiv-dataplatform.20210525.13-41-47.txt

I tried connecting to the API Playground. This is not working as well:

I may be able to setup a test from my private pc tomorrow. It is not so easy to avoid the corp network.

Hi @Merijn

I have discussed your issue with the RDP Lib Dev team and they have requested additional logging information,

Can you please add the following extra two lines to the start of your script and capture the output again, please

import logging
logging.basicConfig(format='%(asctime)s - %(name)s - %(levelname)s - %(message)s', level=logging.DEBUG)

import os
os.environ["HTTPX_LOG_LEVEL"] = "TRACE"

import refinitiv.dataplatform as rdp

#....
#open platform session etc...
#....

Please remove all 'authorization', b'Bearer sections from any output before uploading (looks like a very long line of alphanumeric output).

Thanks.

Hi Umer,

I tried with the addtional login, but I don't see any additional output. When I run this code I get the following response - see attached log file created.

import os
import rf_settings as settings
import refinitiv.dataplatform as rdp
import logging
logging.basicConfig(
    format='%(asctime)s - %(name)s - %(levelname)s - %(message)s', level=logging.DEBUG)

print(rdp.__version__)
rdp.open_platform_session(
    settings.APP_KEY,
    rdp.GrantPassword(
        username=settings.RDP_LOGIN,
        password=settings.RDP_PASSWORD
    )
)
universe = ['EUR=']
fields = ['ASK', 'BID']
response = rdp.Pricing.get_snapshot(universe, fields)
print(response.data.df)
rdp.close_session()

Hi @Merijn

Thanks for trying that - but for some reason, the additional trace output is not being generated on your PC. I have asked the RDP Library team for more guidance.

Were you able to try the code on a non-corporate network?

Also, what error message do you see if you try to post the following into your browser on your corporate network?

https://api.refinitiv.com/data/pricing/beta3/snapshots?universe=EUR%3D&fields=ASK%2CBID

Are you able to contact your internal network security and ask them to assist you as well - in terms of firewall / proxy help?

Hi Umer,

I have not tried setting up RDP outside of the corporate network yet. That will take some more time. I hope we can find another way to test this.

When I try the URL on the server I get the following return message:

I tried to run the code from my local machine (with Anaconda) - outside the corporate environment. In this case the logon to Refinitiv is failing.
