Error message

No data found for the provided dates. Data has a range from {df.date.min()} to {df.date.max()}.

What it means

EmptyDataError raised at the end of EconDbPortVolumeFetcher.transform_data: after mapping countries and applying start_date/end_date filters, the DataFrame has zero rows, and the message reports the dataset's actual min/max dates. The data exists but lies outside your requested window (dataset starts 2022-04-04; see the query-param validator in the same file).

Solutions

Read the min/max dates from the error message and set your window inside that range.
Omit dates to fetch the full range, then filter locally.
Keep end_date at least a few days before today to account for publication lag.

Example fix

# before
obb.economy.port_volume(provider='econdb', start_date='2026-08-10', end_date='2026-08-14')  # likely unpublished week

# after
obb.economy.port_volume(provider='econdb')  # full range; filter locally afterwards

Defensive patterns

Strategy: validation

Validate before calling

full = obb.economy.port_volume(provider='econdb').to_df()
lo, hi = full['date'].min(), full['date'].max()
if not (lo <= start_date <= hi) or not (lo <= end_date <= hi):
    start_date, end_date = max(start_date, lo), min(end_date, hi)

Try / catch

from openbb_core.provider.utils.errors import EmptyDataError
try:
    res = obb.economy.port_volume(provider='econdb', start_date=s, end_date=e)
except EmptyDataError as err:
    # message contains the true range: 'Data has a range from X to Y.'
    logger.warning(str(err))
    res = obb.economy.port_volume(provider='econdb')

Prevention

Parse the reported min/max range out of the error and re-query inside it.
Account for weekly publication lag on end_date.
Fetch full range once, cache it, and slice locally.

When it happens

Trigger: economy.port_volume(provider='econdb', start_date/end_date) filtering out all rows: end_date before 2022-04-04, start_date after the dataset's last date, or a window narrower than the weekly data points.

Common situations: Recent end_date beyond the latest published week; windows that fall between weekly data points; assuming longer history than 2022-04-04.
