must be finite, positive and within

Error message

{name} must be finite, positive and within {limit}

What it means

Range guard in validate_settings: one of frames (<=108000), width/height (<=16384), or fps (<=240) is non-numeric, boolean, non-finite, outside 1..limit, or (except fps) not a whole number. The parameter name at fault is in the message.

Solutions

1. Fix the named parameter to a positive finite value within its stated limit
2. Ensure integer arguments (frames, width, height) are whole numbers

When it happens

Trigger: Thrown at skills/taste-application/scripts/blender_prop.py:103 when the library encounters an invalid state.
