@dewi
Thank you for reaching out to us.
The error is similar to the error on this discussion.
It may relate to the version of httpx installed on a Python environment. Therefore, please check the version of httpx.
C:\Users\U8009686>pip show httpx WARNING: Ignoring invalid distribution ~lotly (C:\Python312\Lib\site-packages)Name: httpx Version: 0.26.0 Summary: The next generation HTTP client. Home-page: https://github.com/encode/httpx Author: Author-email: Tom Christie <tom@tomchristie.com> License: Location: C:\Python312\Lib\site-packages Requires: anyio, certifi, httpcore, idna, sniffio Required-by: eikon, jupyterlab, lseg-data, refinitiv-data, refinitiv-dataplatform
should we set up the proxy or what's I don't get any answer from the discussion that you attached
The client didn't share the resolution but I understand it should relate the proxy settings or dependency libraries.
You can check the version of httpx when the problem occurred on this page.
When you got the error, please run the following code on the same page.
import httpx print(httpx.__version__)
The version is 0.26.0
Can you share the full call stack?
I need to make sure that it is the same issue.

Hello @dewi
Can you try with the latest https://developers.lseg.com/en/api-catalog/lseg-data-platform/lseg-data-library-for-python ( https://pypi.org/project/lseg-data/ ) which is the Data Library version 2?
The library interfaces are mostly the same as Refinitiv Data Library (Data Library version 1) except the get_data() method requires the fields parameter.
I strongly suggest you try with a new Python virtual environment (venv or conda).
I already use the lseg data but got the same issue
I assume that you are using the Databricks.
I tested it on Azure Databricks and it works fine.
You may try to downgrade the httpx to 0.24.1 and then restart the environment.
I already following you setup session and downgrade the httpx, also restart the kernel but I got this error messages How to setup the session? Could you share the clearly documentation?
[Error 400] - {'error': 'access_denied'}Session is not opened. Can't send any requestValueError: Session is not opened. Can't send any request
The issue may be specific to your environment.
Could you specify which Python environment or distribution you're currently using?
You may try to test it on another environment.
Did the error change?
the error change to this[Error 400] - {'error': 'access_denied'}Session is not opened. Can't send any requestValueError: Session is not opened. Can't send any request
It typically means that the credentials (user name and password) are incorrect.
You can check your credentials by accessing this website (https://apidocs.refinitiv.com/Apps/ApiDocs).
How did you solve the first issue (AttributeError: 'dict' object has no attribute 'url')?
https://apidocs.refinitiv.com/Apps/ApiDocs when I access this link I got an authentication denied
I follow step by step, username and password is correct but I got access denied
If you are getting authentication denied when using API Playground, this means that your credentials are incorrect.
