Error going from desktop.workspace to platform.deployed

Hello,


I am using the Refinitiv Data Api. I have no issue running the following script on my machine (when Eikon Desktop is running)

import refinitiv.data as rd

rd.open_session('desktop.workspace')

rd.get_data(

universe=['USDSROISTNZ=R'],

fields=['PRIMACT_1']

)

I get a dataframe of the data that I am looking for, so all good.


When I try to run the following

rd.open_session('platform.deployed')

rd.get_data(

universe=['USDSROISTNZ=R'],

fields=['PRIMACT_1']

)

the code gets stuck and it does not give me any output or error, simply gets stuck (probably in an endless loop).


This is are the components of the refinitiv-data.config.json file. I am using the same app key (It's an Eikon Data API key). Url and Dacs are coming from the market data team in my company

"desktop": {

"workspace": {

"app-key": "#### APP KEY ####"

}

}


"deployed": {

"app-key": "#### APP KEY ####",

"realtime-distribution-system": {

"url" : " xxx.xx.xxx.x:xxxxx",

"dacs" : {

"username" : "xxxxxx",

"application-id" : xxx,

"position" : ""

}

}

}




Any idea what is happening?

Hi @lucio.fiorin

I notice a space in your URL

ws:// xxx.xx.xxx.x:15000/WebSocket

If there is a space in your json file, please try removing it

ws://xxx.xx.xxx.x:15000/WebSocket

Hi,

Agree, the space was causing problems. Now it is able to connect.

I am trying the following code as suggested:

stream = rd.open_pricing_stream(

universe=['USDSROISTNZ=R'],

fields=['PRIMACT_1'],

on_data=display_data

)


but I get the following error(s)

Hi @lucio.fiorin,

The 'platform.deployed' specification refers to sessions that connect directly to your own deployed streaming service. The 'deployed' configuration does not require an 'app-key'. If you are attempting to connect to your own deployed streaming service and want to get prices, you will need to utilize the pricing interfaces:

Hi @lucio.fiorin

As your organisation's real-time servers probably have more than one service being published (and no default specified), you will need to specify the service you wish to consume data from


stream = rd.open_pricing_stream(
    universe=['GBP=', 'EUR=', 'JPY='],
    fields=['BID', 'ASK'],
    service='ELEKTRON_DD',
    on_data=display_data
)

Please check with your Market Data team that ELEKTRON_DD is indeed the correct service name to use.

Also, check your dacs id also does not have a leading space...

Hello,

I am using the exact same specification suggested by the market data team, not sure how they can get a result running the same script then.

I was able to add the logs, I get the following error (I redacted the realtime distribution system url

Hi @lucio.fiorin

Can you confirm there is no space in your actual IP? Appears to be there again:
