The request was returned empty.

Error message

The request was returned empty.

What it means

EmptyDataError raised in IntrinioEquityHistoricalFetcher.transform_data when the raw data list is empty after fetch. The API call succeeded (no error key) but returned zero bars for the symbol/parameters, so there is nothing to sort on the date/time column or validate into IntrinioEquityHistoricalData.

Solutions

1. Set start_date/end_date to a window where the security actually traded
2. Verify listing dates for the symbol and clamp your request range
3. Catch EmptyDataError and skip/continue in batch loops — it is a normal 'no rows' outcome, not a bug

Example fix

# before
df = obb.equity.price.historical(provider="intrinio", symbol="TSLA", start_date="1999-01-01", end_date="1999-02-01").to_df()

# after
df = obb.equity.price.historical(provider="intrinio", symbol="TSLA", start_date="2024-01-01", end_date="2024-02-01").to_df()

from datetime import datetime, timedelta

def plausible_date_range(symbol_listed: datetime, start: str, end: str) -> bool:
    s, e = datetime.fromisoformat(start), datetime.fromisoformat(end)
    return s < e and s >= symbol_listed and e <= datetime.now() + timedelta(days=1)

from openbb_core.provider.utils.errors import EmptyDataError

try:
    bars = await obb.equity.price.historical(provider="intrinio", symbol=sym, start_date=s, end_date=e)
except EmptyDataError:
    bars = []  # no rows in window — expected outcome

When it happens

Trigger: Valid symbol with no price rows in the requested window (date range before listing, weekend-only range for daily bars, or a range with no trading data); a frequency/interval combination that yields no rows; thinly traded securities.

Common situations: Backtesting scripts looping over date windows that run past a ticker's listing date; requesting daily bars for a window entirely on weekends/holidays; using a newly listed ticker with an old start_date.
