Invalid country, {country}, must be one of {list(COUNTRIES_D

Error message

Invalid country, {country}, must be one of {list(COUNTRIES_DICT)}

What it means

EconDbYieldCurveQueryParams.validate_country raises ValueError for any comma-separated country token not present in COUNTRIES_DICT (the provider's supported yield-curve countries). Validation runs at query construction, so the error surfaces before any network call; the message lists all accepted values.

Solutions

1. Read the accepted values from the error message and use one exactly (e.g. 'united_states').
2. Query only countries you know EconDB publishes yield curves for (a small set — the message enumerates it).
3. For multiple countries pass a comma-joined string of valid keys: 'united_states,japan'-style values drawn from the listed set.

Example fix

# before
obb.economy.yield_curve(provider='econdb', country='US')

# after
obb.economy.yield_curve(provider='econdb', country='united_states')

from openbb_econdb.models.yield_curve import COUNTRIES_DICT
requested = ['united_states', 'japan']
invalid = [c for c in requested if c not in COUNTRIES_DICT]
if invalid:
    raise ValueError(f'econdb yield curve supports only {list(COUNTRIES_DICT)}; got {invalid}')

def is_supported_yield_country(c: str) -> bool:
    from openbb_econdb.models.yield_curve import COUNTRIES_DICT
    return c in COUNTRIES_DICT

try:
    res = obb.economy.yield_curve(provider='econdb', country=country)
except Exception as e:
    if 'must be one of' in str(e):
        country = 'united_states'
        res = obb.economy.yield_curve(provider='econdb', country=country)
    else:
        raise

When it happens

Trigger: economy.yield_curve(provider='econdb', country='usa'/'US'/'japan') — the dict keys are specific identifiers (e.g. 'united_states'); any other spelling is rejected.

Common situations: Using ISO codes or display names from other providers; typo; assuming case-insensitivity (the check is exact).
