No valid countries were supplied.

Error message

No valid countries were supplied.

What it means

EconDbGdpNominalFetcher's country normalization (economy/gdp_nominal.py) removes every supplied country that it cannot map: 3-letter codes not in THREE_LETTER_ISO_MAP are dropped, and strings that are neither 2-letter ISO codes, COUNTRY_MAP names, nor COUNTRY_GROUPS keys never match. If the list ends up empty, OpenBBError('No valid countries were supplied.') is raised before any network call.

Solutions

1. Use 2-letter ISO codes (e.g. 'us', 'pt') — they pass through normalization directly.
2. For full names, use underscore form matching COUNTRY_MAP keys (e.g. 'united_states'), lowercase.
3. For groups, use a COUNTRY_GROUPS key such as 'g20'.
4. Capture warnings to see exactly which supplied codes were rejected.

Example fix

# before
obb.economy.gdp_nominal(provider='econdb', country='USA')  # may fail if 'USA' misses THREE_LETTER_ISO_MAP

# after
obb.economy.gdp_nominal(provider='econdb', country='us')  # or 'united_states', or 'g20'

from openbb_econdb.utils.helpers import COUNTRY_MAP, COUNTRY_GROUPS
from openbb_econdb.utils.helpers import THREE_LETTER_ISO_MAP  # if exported; else validate against COUNTRY_MAP keys

def normalize(c: str) -> str | None:
    c = c.lower()
    if len(c) == 2 or c == 'g20':
        return c
    if len(c) == 3 and c != 'g20':
        return THREE_LETTER_ISO_MAP.get(c.upper(), None)
    if c in COUNTRY_MAP:
        return COUNTRY_MAP[c].upper()
    if c in COUNTRY_GROUPS:
        return ','.join(COUNTRY_GROUPS[c])
    return None

countries = [c for c in map(normalize, inputs) if c]

When it happens

Trigger: Calling economy.gdp_nominal(provider='econdb', country='ZZ' or country='usa' variants that miss the maps) where every entry fails normalization. Note each invalid code also emits a warnings.warn('Error: X is not a valid country code.') before the raise.

Common situations: Typos in country names ('unitedstates' instead of 'united_states'), unsupported 3-letter codes, passing a region name not present in COUNTRY_GROUPS, or case-sensitivity mistakes for names longer than 3 characters.
