Error message

market target must be one of cn, hk, us, jp, kr: {region}

What it means

ValueError(f'market target must be one of cn, hk, us, jp, kr: {region}') with code validation_error is raised by normalize_market_region (src/services/market_light_service.py:24) when the requested market region, after strip().lower(), is not in MARKET_LIGHT_REGIONS = {'cn','hk','us','jp','kr'}. This is the entry-point validation for building/loading Market Light snapshots.

Solutions

1. Use one of the five supported region codes: cn, hk, us, jp, kr (case-insensitive, whitespace tolerated)
2. Map upstream market identifiers to these codes before calling (e.g. 'SHA'/'Shanghai' -> 'cn')
3. If you need another region, extend MARKET_LIGHT_REGIONS and the analyzer support deliberately — not by bypassing the check

Example fix

# before
build_current_snapshot("china")

# after
build_current_snapshot("cn")

from src.services.market_light_service import MARKET_LIGHT_REGIONS

region = region.strip().lower()
if region not in MARKET_LIGHT_REGIONS:
    raise ValueError(f"region must be one of {sorted(MARKET_LIGHT_REGIONS)}")

from src.services.market_light_service import MARKET_LIGHT_REGIONS

def is_supported_market_region(region: str) -> bool:
    return isinstance(region, str) and region.strip().lower() in MARKET_LIGHT_REGIONS

try:
    snapshot = build_current_snapshot(region)
except ValueError as exc:
    if "market target must be one of" in str(exc):
        return api_error(400, "supported regions: cn, hk, us, jp, kr")

When it happens

Trigger: Calling build_current_snapshot or snapshot-loading helpers with region values like 'a', 'CN ' (fine after trim), 'sh', 'china', 'gb', or an empty string/None (str(None) -> 'none').

Common situations: Passing stock-exchange codes instead of region codes, localized country names ('日本'), or regions added in a newer version being sent to an older deployment.
