Error message

Error: The no data was found for the supplied symbols and countries: {query.symbol.split(',')} {query.country.split(',') if query.country else ''}

What it means

EmptyDataError from EconDbEconomicIndicatorsFetcher.transform_data: raw records arrived, but after per-symbol cleaning, transformation alignment and dropna, the combined `output` DataFrame is empty. The message embeds the requested symbols and countries (as Python lists, due to f-string of .split(',')).

Solutions

1. Widen the date range well beyond the transformation lag (e.g. +1 extra year for YoY).
2. Retry without the '~transform' suffix to confirm raw levels exist for the window.
3. Query each symbol separately to isolate which one collapses to empty after dropna.
4. Treat EmptyDataError as 'no observations' and continue in batch jobs.

Example fix

# before
res = obb.economy.indicator(provider="econdb", symbol="cpi~yoy", country="us", start_date="2024-01-01", end_date="2024-03-01")  # YoY lag -> all NaN

# after
res = obb.economy.indicator(provider="econdb", symbol="cpi~yoy", country="us", start_date="2022-01-01", end_date="2024-03-01")

TRANSFORM_LAG_YEARS = {"yoy": 1, "ytd": 1}  # conservative

def range_covers_transform(start, end, transform: str | None) -> bool:
    lag = TRANSFORM_LAG_YEARS.get((transform or "").lower(), 0)
    return (end.year - start.year) >= lag

from openbb_core.provider.utils.errors import EmptyDataError
try:
    res = obb.economy.indicator(provider="econdb", symbol=s, country=c, start_date=a, end_date=b).to_df()
except EmptyDataError:
    if "~" in s:  # transform likely ate the window
        res = obb.economy.indicator(provider="econdb", symbol=s.split("~")[0], country=c, start_date=a, end_date=b).to_df()
    else:
        raise

When it happens

Trigger: Calling obb.economy.indicator(provider='econdb', ...) where every fetched series drops to all-NaN — e.g. transform suffixes that produce NaN over the whole window, dates misaligned so dropna removes all rows, or symbols whose observations are all null in the requested period.

Common situations: Year-over-year transforms requested over a window shorter than the transform lag; querying a period before the series started (rows exist in raw payload but are null); mixing symbols whose data ended with ones that haven't started.
