Solutions

1. Provide the field as an integer value, not a string or float.
2. Check the request payload or signal data source for the named field and convert it to an integer before submitting.
3. If the value comes from user input, validate and coerce it with int() after checking isdigit() or a numeric parse.

When it happens

Trigger: Thrown at src/services/decision_signal_service.py:1272 when the library encounters an invalid state.

Common situations: Raised when a decision-signal integer field (e.g. horizon/period) is not an integer; occurs when the client sends a string or float for a field validated in decision_signal_service.
