Dates must be after 2022-04-03.

Error message

Dates must be after 2022-04-03.

What it means

EconDbPortVolumeQueryParams defines a field_validator on start_date/end_date that rejects any date earlier than 2022-04-04, raising OpenBBError('Dates must be after 2022-04-03.'). The EconDB shipping/port-volume dataset simply begins on 2022-04-04, so earlier dates are invalid by construction.

Solutions

1. Set start_date (and end_date) to 2022-04-04 or later.
2. Omit the dates entirely to get the full available range.
3. Branch per provider when sharing date params across providers in one script.

Example fix

# before
obb.economy.port_volume(provider='econdb', start_date='2021-01-01')

# after
obb.economy.port_volume(provider='econdb', start_date='2022-04-04')  # or omit start_date

from datetime import date
ECONDB_PORT_MIN = date(2022, 4, 4)
if start_date and start_date < ECONDB_PORT_MIN:
    start_date = ECONDB_PORT_MIN

from openbb_core.app.model.obbject import OpenBBError
try:
    res = obb.economy.port_volume(provider='econdb', start_date=s)
except OpenBBError as e:
    if 'must be after 2022-04-03' in str(e):
        s = date(2022, 4, 4)
        res = obb.economy.port_volume(provider='econdb', start_date=s)
    else:
        raise

When it happens

Trigger: Calling economy.port_volume(provider='econdb', start_date='2020-01-01') (or any date < 2022-04-04) — the error fires at parameter validation time, before any HTTP request.

Common situations: Reusing a generic default start_date (e.g. 5 years back) from a multi-provider workflow where other providers have longer history; copy-pasting date ranges from other endpoints.
