Error message

The request was returned empty.

What it means

BenzingaCompanyNewsFetcher.a_fetch_data (company_news.py:177) gathers pages concurrently with asyncio.gather; if after all page callbacks `results` is still empty it raises EmptyDataError("The request was returned empty."). Empty means the filters matched no news, or every page errored into the caught OpenBBError/Unauthorized path without aborting. UnauthorizedError, when it occurs, is re-raised as-is upstream of this.

Solutions

1. Catch EmptyDataError and return an empty news list to the UI.
2. Widen date range and confirm tickers; test the same query on a liquid name like AAPL.
3. Check credential health — sustained emptiness across all tickers suggests an auth problem rather than coverage.
4. Page-size sanity: keep a reasonable `size` and iterate `page` rather than one huge filtered request.

Example fix

# before
res = obbject.news.world.query(provider="benzinga", date="2026-08-01")

# after
from openbb_core.provider.standard_models.errors import EmptyDataError
try:
    res = obbject.news.world.query(provider="benzinga", date="2026-08-01")
except EmptyDataError:
    res = []  # no coverage for that window

if not (query.symbols and query.start_date <= query.end_date):
    raise ValueError("invalid company-news filter window")
# coverage probe on a liquid name
probe = await obbject.news.company(symbol="AAPL", provider="benzinga", limit=1)

from openbb_core.provider.standard_models.errors import EmptyDataError
try:
    results = await fetcher.a_fetch_data(query, credentials)
except EmptyDataError:
    results = []  # no news matched the filters

When it happens

Trigger: Querying company news for tickers/date ranges with no coverage, size=0-style degenerate filters, or a date range entirely outside Benzinga's archive for those symbols.

Common situations: Weekend/holiday windows, pre-IPO or delisted tickers, non-US symbols Benzinga news doesn't tag, and typo'd date parameters producing empty windows.
