Unable to obtain DUDETAILSUMMARY

[mdavis-xyz]

Summary

I'm trying to get DUDETAILSUMMARY. When setting and end date past the available data, no data is returned. I expect at least the most recent available file to be returned.

As of today (7/1/2026) the most recent file is PUBLIC_ARCHIVE#DUDETAILSUMMARY#FILE01#202511010000.zip

import datetime as dt
from nemosis import cache_compiler, dynamic_data_compiler
import os


start_time = '2025/01/01 00:00:00'
end_time = '2026/01/01 00:00:00'
table = 'DUDETAILSUMMARY'

dynamic_dir = "data/test/dynamic"
os.makedirs(dynamic_dir, exist_ok=True)
df = dynamic_data_compiler(start_time, end_time, table, dynamic_dir)

Even though the timespan includes multiple eligible files, I get error:

NoDataToReturn: Compiling data for table DUDETAILSUMMARY failed. This probably because none of the requested data could be download from AEMO. Check your internet connection and that the requested data is archived on: https://nemweb.com.au/ see nemosis.defaults for table specific urls.

I suspect nemosis is trying to deduplicate this standing data table for me, but there's a bug in the date calculations to figure out which file to use.
