ValueError: datetime64/timedelta64 values and dtype must have a unit specified

I get an error when trying to retrieve news headlines with Python API. The error only seems to occur on certain time ranges. For example, this works:

import eikon as ek
df = ek.get_news_headlines('Topic:ESG AND Language:LEN', date_from='2022-01-01', date_to='2022-12-01', count=100)

But this does not work (the only difference is the time range):

import eikon as ek
df = ek.get_news_headlines('Topic:ESG AND Language:LEN', date_from='2020-01-01', date_to='2020-12-01', count=100)

This is the error I receive:

Do you have any ideas what could be causing the error?

Hi @essi.rajala ,


Thank you for your question. According to the Eikon Data API Usage and Limits Guideline, The depth of news headline history is 15 month, that is why you don't receive the data for 2020.


Hope this helps.

Best regards,

Haykaz

Hi @essi.rajala ,

I'm sorry to hear that you're facing an issue. However, I was not able to reproduce the issue in my local environment or CodeBook, with the same request.

It seems from the error that it does not originate with the eikon library, but rather with one of the eikon dependencies, suspecting NumPy or pandas.

Would suggest verifying the versions of pandas and NumPy against CodeBook versions as mentioned in this thread

To be of help, below are the current version of the libraries mentioned in the Codebook app

  • Eikon version 1.1.14
  • Pandas version 1.3.5
  • NumPy version 1.22.4
  • Python 3.8.15

Plus, refer to the Eikon Data API Usage and Limits Guideline, the depth of news headlines is 15 months.

get_news_headlines: The current limit value (10-Oct-2019) is 100 headlines per request. The depth of history is 15 month.
