When I try to retrieve data using the Pyhon API, I get a JSONDecodeError. I am using Python 3.8.5 (64-bit) on Windows 10 and version 1.1.6.post3 of the eikon package. The same code worked fine, i.e. produced the expected results, a couple of months ago. I updated the eikon package after I got the error message. But this did not resolve the problem.
The following request
ek.get_timeseries('.STOXX50E', start_date='2018-10-01', end_date='2020-09-30')now produces this error message:
