不支持的数据源: {self.current_source}

Error message

不支持的数据源: {self.current_source}

What it means

Raised by DataSourceManager.get_data_adapter() when self.current_source does not match any known ChinaDataSource enum branch (MongoDB/AKShare/BAOSTOCK; TDX was removed). It is a formatted message where {self.current_source} is interpolated at raise time.

Solutions

1. Set the source to a supported value: mongodb, akshare, or baostock
2. If you depended on TDX, pin the older release or migrate to akshare/baostock
3. Clear persisted datasource config that still stores 'tdx'

Example fix

# before
manager.current_source = 'tdx'
adapter = manager.get_data_adapter()
# after
from tradingagents.dataflows.datasource_config import ChinaDataSource
manager.current_source = ChinaDataSource.AKSHARE
adapter = manager.get_data_adapter()

from tradingagents.dataflows.datasource_config import ChinaDataSource
valid = {s.value for s in ChinaDataSource}
if manager.current_source not in valid:
    raise ValueError(f'unsupported source; choose from {sorted(valid)}')
adapter = manager.get_data_adapter()

def is_supported_source(src) -> bool:
    from tradingagents.dataflows.datasource_config import ChinaDataSource
    return src in list(ChinaDataSource)

try:
    adapter = manager.get_data_adapter()
except ValueError as e:
    if '不支持的数据源' in str(e):
        manager.current_source = ChinaDataSource.AKSHARE
        adapter = manager.get_data_adapter()
    else:
        raise

When it happens

Trigger: Setting the data source to a stale value like 'tdx' or 'TDX' (removed), an arbitrary string not in ChinaDataSource, or a value loaded from persisted config written by an older version.

Common situations: Upgrade after TDX removal but old config/env still selects it; user typo in the datasource setting; enum member renamed between versions.
