Troubleshooting

Common Issues

  1. JSON parsing errors in MCP mode

    # Ensure MCP mode is enabled IDX_MCP_LOG_LEVEL=error npx @baguskto/saham

  2. Historical data not loading

    # Clear cache and retry npx @baguskto/saham clear-cache # Test GitHub connectivity npx @baguskto/saham test

  3. Yahoo Finance timeouts

    • Increase timeout in configuration

    • Check internet connectivity

    • Use debug mode for diagnosis
