Hi,
I encountered this error calling
ek.get_timeseries(['URBN.O'],interval='minute',start_date='2019-02-26T14:45:01',end_date='2019-02-26T14:50:01')
what does the error mean and how to resolve it?
This means the backend was unable to service the request. From the client side there's no way to tell what the root cause may have been at the backend. All you can do is try the same request again later.
