Client is using Jupyter API

I'm not able to download date using this code. This was possible a couple of months ago.

importrefinitiv.data as rd

rd.open_session()

st="JPUSTOSR21M=TTKL"

dt1="2025-07-06"

dt2="2025-07-09"

start_dt = dt1 +"T00:00:00" end_dt = dt2 +"T20:59:59" df =rd.get_history(st, fields=['BID','ASK'], interval="tick", start =start_dt, end = end_dt)

Client encountered an error:

Hello @RALPHPAOLO.NAVARRO

The instrument JPUSTOSR21M=TTKL seems to be invalid. I can't find it or get any data for it. Please reach out to content specialist at LSEG MyAccount, to get the correct symbol.

@Gurpreet can you try using EUR1YOIS=FMD please. thank you so much

Hi @RALPHPAOLO.NAVARRO ,

I can retrieve data properly with the RIC you provided

RALPHPAOLO.NAVARRO

hello team. @Gurpreet @raksina.samasiri

Client followed up, I tried to execute this code:

# Start session with your App Key

from IPython.display import HTML

import pandas as pd

import refinitiv.data as rd

session= rd.open_session(app_key=xxxxxxxxx)

print(session)

I got this message:

DesktopSession

name = 'workspace'

connection = DesktopConnection

stream_auto_reconnection = True

handshake_url = http://localhost:9000/api/handshake

state = OpenState.Pending

session_id = 0

logger_name = sessions.desktop.workspace.0

As you can see, the state is Pending.

Can you please assist to fix this?

Thank you

The error (Error code -1 | 'dict' object has no attribute url') is similar to this discussion.

The client should migrate the application to use the LSEG Data Library for Python instead. The examples are available on GitHub.

To migrate the application, please refer to this Essential Guide to the Data Libraries - Generations of Python library (EDAPI, RDP, RD, LD) article.

Hi Sir @Jirapongse @Gurpreet

As per client,

I’m able to fetch market data if I use CODEBK. However, I use Jupyter or Visual Studio Code. Lseg librairy is no longer accessible.

This is the code I used, but it doesn’t work. Can you please assist?

import lseg.data as ld

ld.open_session(config={"app_key": "REMOVED"})ld.get_history("LSEG.L")

@RALPHPAOLO.NAVARRO

Please share the error.

Hello good morning @Jirapongse @Gurpreet

This is error client got when executing this code:

Cell In[61], line 2

ld.open_session(config={"app_key": "<app_key>"})ld.get_history("LSEG.L")

SyntaxError: invalid syntax

REMOVED

Thank you for your assistance.

Jirapongse

The code should be like this:

import lseg.data as ld

ld.open_session(app_key = "<APP KEY>")

ld.get_history("LSEG.L")

You may try to downgrade the httpx to 0.24.1.
