EventVestor EarningsCalendar error in pipeline

Seeking Help Using Data Pipeline

Hi all,

I am having an issue with EventVestor EarningsCalendar data in the pipeline. Specifically, using the earnings calendar data in any form results in an assertion error. This occurs with my own notebooks as well the example notebooks on the EarningsCalendar page.

Any help would be appreciated as I am at a complete loss.

Reported error is as follows:

ValueError: Bad response: Computation failed with message:

Hi Ian

This error is something we've started to see recently - it seems to a problem specific to our production environment.

We're quickly working on a solution.

Best,
Matt

Hi Matt,

Thanks for the update. It would be useful if you offered a dashboard on the status of the platforms as well as data sources, so that we could check the progress ourselves. Perhaps I missed the link!

Cheers,
Ian Lloyd
