Error message

No results found. Try adjusting the query parameters.

What it means

Raised as EmptyDataError by FederalReserveFederalFundsRateFetcher.aextract_data when the NY Fed markets API (/api/rates/unsecured/effr/search.json) returns no 'refRates' entries for the requested start/end dates. OpenBB surfaces this as the standard 'No results found. Try adjusting the query parameters.' message.

Solutions

1. Widen or shift the date range to covered dates (EFFR starts 2016-07; the API also serves OBFR/other tenors from similar dates).
2. Check the raw JSON at https://markets.newyorkfed.org/api/rates/unsecured/effr/search.json?startDate=...&endDate=... to see whether refRates is empty upstream.
3. Handle EmptyDataError in the caller and treat it as zero rows rather than a failure.

from datetime import date
start = max(start_date, date(2016, 7, 1))  # EFFR coverage begins July 2016
if start > end_date:
    raise EmptyDataError('range predates EFFR coverage')

from openbb_core.provider.standard_errors import EmptyDataError
try:
    res = obb.economy.fed.fed_funds_rate(start_date=start, end_date=end)
except EmptyDataError:
    res = None  # no published rates in range

When it happens

Trigger: Querying the EFFR rate with a date range entirely before 2016 (EFFR history starts ~July 2016), a future date range, or a range with no published rates (e.g. weekends/holidays only if very narrow).

Common situations: Default date ranges pulled from other series (e.g. 2000 start) applied to EFFR; overnight-rate data requested over weekends only; date strings malformed so the API filters everything out.
