Solutions

1. Ensure the named field contains valid JSON text before saving or parsing.
2. Fix the stored record: re-save the field as serialized JSON rather than a Python repr or truncated string.
3. If the field should be optional, pass null/empty instead of malformed JSON.

When it happens

Trigger: Thrown at src/services/history_service.py:503 when the library encounters an invalid state.

Common situations: Raised when a JSON field stored on a history record cannot be parsed; occurs when legacy or corrupted rows contain malformed JSON in raw_result or related fields.
