Error message

"\n".join(messages)  # messages contain e.g. 'No data was returned for, {country}' or 'The response for, {country}, was returned empty.'

What it means

EconDbYieldCurveFetcher.aextract_data raises OpenBBError with all accumulated per-country messages joined by newlines when every requested country failed (no results at all). The messages are of the form 'No data was returned for, {country}' (falsy response) or 'The response for, {country}, was returned empty.' (no 'results' key) — so the real cause is in the message body, not the exception type.

Solutions

Set date to the most recent business day (or omit it — transform_query defaults to today, so pass an explicit recent weekday if today fails).
Read each line of the message to identify whether all countries failed the same way.
Retry once in case the temp token was bad; or supply your own econdb_api_key credential.
Reduce to a single known-good country (e.g. 'united_states') to isolate the issue.

Example fix

# before
obb.economy.yield_curve(provider='econdb', date='2026-08-15')  # Saturday - no curve published

# after - most recent business day
obb.economy.yield_curve(provider='econdb', date='2026-08-13')

Defensive patterns

Strategy: try-catch

Validate before calling

from datetime import date, timedelta
d = query_date or date.today()
while d.weekday() >= 5:  # back up to last weekday
    d -= timedelta(days=1)

Try / catch

from openbb_core.app.model.obbject import OpenBBError
try:
    res = obb.economy.yield_curve(provider='econdb', country=','.join(cs), date=d)
except OpenBBError as e:
    for line in str(e).splitlines():  # per-country diagnostics
        logger.warning(line)
    raise

Prevention

Always request recent business-day dates for yield curves.
Split multi-country requests so one bad country does not sink all.
Check each newline in the message - it names the failing countries.

When it happens

Trigger: economy.yield_curve(provider='econdb', country='...', date=D) where D falls on a weekend/holiday/unnegotiated day so every country's series response comes back empty; or a bad/expired token making all per-country API calls return nothing.

Common situations: Querying today's date when no curve was published (weekend/holiday); invalid temp token from create_token; date far in the past or future for all requested countries.
