The request was returned empty.

Error message

The request was returned empty.

What it means

Raised in FREDSOFRFetcher.transform_data (openbb_fred/models/sofr.py:210) when the dict handed from extract_data is falsy - the delegated FredSeriesFetcher returned no metadata/data payload for the SOFR series (SOFR, from the FRBNY/Secured Overnight Financing Rate dataset). An EmptyDataError meaning the upstream series request yielded nothing, most commonly due to rate limiting or a temporarily unavailable series.

Solutions

1. Retry after a minute to rule out rate limiting.
2. Remove or widen start_date/end_date, ensuring the range intersects 2018-present.
3. Update the openbb package if SOFR series mapping changed upstream.

from openbb_core.provider.utils.errors import EmptyDataError
import time

try:
    res = obb.economy.fred.sofr(start_date=s, end_date=e)
except EmptyDataError:
    time.sleep(60)
    res = obb.economy.fred.sofr()

When it happens

Trigger: Calling economy/fred sofr while rate limited; the SOFR series ID changing upstream; an empty date range from aggressive start/end filters.

Common situations: Automated daily rate pulls hitting the FRED request cap; the date range not overlapping SOFR's history (published since 2018).
