No instruments found in catalog for requested IDs: [{}]

Error message

No instruments found in catalog for requested IDs: [{}]

What it means

Guard in the backtest node's build_engine: the data catalog query returned no instruments for the instrument IDs requested by the run config, so the backtest would have no tradable data and engine construction is aborted.

Solutions

1. Check the instrument IDs match the catalog's instruments (correct venue/symbol)
2. Verify the data catalog path and that instrument data was written to it
