Solutions

1. Inspect the raw BGPT response; it must contain the expected results array.
2. Handle empty or missing results explicitly before iterating.

Example fix

data = resp.json()
results = data.get('results')
if not isinstance(results, list):
    raise Exception('Invalid results format from BGPT')

When it happens

Trigger: Thrown at agent/tools/bgpt.py:107 when the library encounters an invalid state.

Common situations: BGPT API contract changes or partial responses lack the expected results field; checking the structure with isinstance before use prevents this error.
