Error code 2504 | UDF Core request failed. Gateway Time-out

Gijs · 2025-05-02T11:53:05+00:00

There was an error rendering this rich post.

Good day, could you please advise on the below error message and how this can be resolved?

eikon.eikonError.EikonError: Error code 2504 | UDF Core request failed. Gateway Time-out

In addition, would like to move over to LSEG Data library API but this is not possible unfortunately. 'I can’t move to the lseg library because you have a dependency of pandas 2<3, which breaks other parts of my code. ' Please advise

Kind regards,

Gijs

Thank you for reaching out to us.

Regarding the Error code 2504, If this problem occurs consistently, please share the code that the client is using. Otherwise, the problem could be on the backend service so the client can use the try/except to catch this error and then re-request.

The client can use the previous versions of LSEG Data Library for Python, such as lseg-data==2.1.0 or lower versions.
