I've been working with the lseg.data API in Python and encountered an issue where I need to add my ID to the code. Despite collaborating with the Product Specialist, the problem persists. The API connection works for other fields like TR.TotAssets, but fails when retrieving data for TR.EventStartDate for specific instruments like AAPL.O.
The error message that I obtain reads as follows:
Error processing Data for permID 4296416132: Error code 221 | The access to field(s) denied. Requested universes: ['4296416132']. Requested fields: ['TR.EventType', 'TR.EventTitle', 'TR.EventStartDate', 'TR.EventLastUpdate']
Since I am working with Linux, I am connecting to API using the config file using ldpv1auth.
ld.open_session(name="platform.ldpv1auth", config_name="/home/alessandro/Dropbox/Coco bonds/Data/Eikon/Configuration/lseg-data.config.json")
Note that other variables can be obtained, so connection to the API is working.
Steps Taken:
- Code Review: Shared the problematic code snippet with the support team.
- Environment: Confirmed that the issue occurs on a Linux system.
- API Connection: Verified that the API connection is functional for other data fields.
- Error Isolation: Identified that the error occurs specifically when retrieving
TR.EventStartDate.
Code Snippet:
params = {'SDate': '2005-01-01', 'EventType': 'ALL', 'EDate': '2025-03-17'}
response, err = fundamental_and_reference.Definition( ["AAPL.O"], "TR.EventStartDate", params).get_data()
Next Steps:
I have been advised by the support team to reach out to the Developer Team via the LSEG Developer Community for further assistance.
Request:
If anyone has encountered a similar issue or has insights into resolving this, please share your experiences or suggestions.
Additional Information:
- Operating System: Linux
- API Fields Tested:
TR.TotAssets (works), TR.EventStartDate (fails) - Support Case Reference: Case 14555990
Thank you for your assistance!
Best regards,
Alessandro
