Error message

No data was found for the supplied date range and countries.

What it means

EmptyDataError from EconDbGdpRealFetcher.transform_data: rows were fetched successfully but the start_date/end_date filter reduced the DataFrame to zero rows. Purely a date-window mismatch — the data exists outside the requested range.

Solutions

1. Query without dates first to learn the series' actual coverage.
2. Align start_date/end_date to quarter boundaries of available data.
3. Lag end_date back one or two quarters for freshly released periods.

Example fix

# before
obb.economy.gdp_real(provider='econdb', country='us', start_date='2026-08-01', end_date='2026-08-31')  # between quarterly points / unpublished

# after
obb.economy.gdp_real(provider='econdb', country='us', start_date='2024-01-01')  # window with published quarters

full = obb.economy.gdp_real(provider='econdb', country='us').to_df()
lo, hi = full['date'].min(), full['date'].max()
start_date = max(start_date, lo)
end_date = min(end_date, hi)

from openbb_core.provider.utils.errors import EmptyDataError
try:
    res = obb.economy.gdp_real(provider='econdb', country='us', start_date=start_date)
except EmptyDataError:
    res = obb.economy.gdp_real(provider='econdb', country='us')
    df = res.to_df(); df = df[df['date'] >= start_date]

When it happens

Trigger: economy.gdp_real(provider='econdb', start_date/end_date) covering a period with no observations: dates before the series start, dates after the last published quarter, or a narrow window between quarterly observations.

Common situations: Sentinel start dates ('1900-01-01'); expecting current-quarter data that is not yet released; quarterly granularity missing a daily-precision window.
