BUG Eikon python package : using get_timeseries method with start_date > end_date

guillaume.lefur

HI team,

There is a strange behavior when we use get_timeseries method with start_date > end_date, It raise an AttributeError and not a ValueError. This happens since you raise seems to raise the ValueError inside a context manager as following (your code in eikon.time_series.py):

Since str has no attribute __enter__, you can't raise that expected ValueError.

To reproduce the issue (eikon version 1.1.14):

import eikon as ek
import datetime

date_format = "%Y%m%d"
start_date = datetime.datetime.strptime("20220415", date_format)
end_date = datetime.datetime.strptime("20220414", date_format)

ek.set_app_key(API_KEY)
result = self.connection.get_timeseries(
                rics=["IBM"],
                fields=["OPEN", "CLOSE"],
                start_date=start_date,
                end_date=end_date,
                raw_output=True,
                normalize=True,
                debug=True,
            )

Thanks

Hi @guillaume.lefur ,

I've tested that this code is run successfully on Eikon Data API version 1.1.16

Hence, I'm closing this thread, please create a new question in case you have any further question

hi @guillaume.lefur ,

Would you mind changing the code from

result = self.connection.get_timeseries(

to

result = ek.get_timeseries(

I've tried it and got an exception ValueError as the screenshot below

Please let me know in case you have any further questions

guillaume.lefur

About self.connection, it's an intern usage equivalent to your ek (i.e self.connection == ek), but the issue is not here.

And from our screenshot, its an AttributeError that has been raised, not a ValueError. ValueError is visible in your code indeed, but that's not the raised error (look at your traceback...)

Yes, you are correct. It should throw the ValueError, not the AttributeError. I have submitted a new case on your behalf to the Eikon Data API support team to verify the code. The case number is 11165341.

The support team will contact you regarding this issue.

@guillaume.lefur issue has been fixed on Eikon Data API v1.1.16 and it's ready on pyp, please upgrade your library to have a test.
