The request was returned with no data.

Error message

The request was returned with no data.

What it means

Raised by FredAmeriborFetch.transform_data when data['data'] is falsy - the FRED series fetch returned a payload whose 'data' mapping (date -> AMERIBOR rates) is empty, so there is nothing to melt into observations. The check happens before the pandas melt/pivot that builds the AnnotatedResult.

Solutions

1. Check the series on fred.stlouisfed.org (AMERIBOR, AMBOR30, AMBOR90) for the actual observation date range and query within it
2. Widen start_date/end_date or remove them to get the full history
3. Shift the requested window a few days earlier to account for publication lag
4. Retry later - FRED observations can lag real time by days

from pandas import DataFrame
raw = fetch_fred_series(['AMERIBOR', 'AMBOR30', 'AMBOR90'], start_date, end_date)
assert raw.get('data'), 'no AMERIBOR observations in window - widen dates'

def has_observations(payload: dict) -> bool:
    return bool(payload.get("data"))

from openbb_core.provider.utils.errors import EmptyDataError
try:
    obs = await obb.fixedincome.ameribor(provider='fred', start_date=s, end_date=e).await_to_list()
except EmptyDataError:
    obs = []  # widen window or shift earlier

When it happens

Trigger: Querying the AMERIBOR fetcher with a date range outside FRED's coverage for those series IDs (AMBOR30/AMBOR90 etc.), or a start_date after the series' last observation (some AMERIBOR tenors were discontinued).

Common situations: Requesting recent dates for discontinued AMERIBOR tenor series (e.g. AMBOR30T/AMBOR90T replaced over time); overly narrow date windows between business days; FRED series temporarily empty during publication lags.
