CT: assertion failure in Easing.polynomialEaseInOutValue #210

Closed pixelzoom closed 5 years ago

pixelzoom commented 5 years ago

This popped up once in CT yesterday. Haven't seen it previously or since, and there have been no changes to unit-rates or twixt. Over in https://github.com/phetsims/twixt/issues/22, I've added a message to the failed assertion in TWIXT/Easing, so we'll get more info if it happens again.

Stack trace:

The failing assertion in Easing was:

Easing.polynomialEaseInOutValue = function( n, t ) {
  assert && assert( typeof t === 'number' && isFinite( t ) && t >= 0 && t <= 1 );

@KatieWoe if you happen to see this error again in CT and I miss it, please paste the stack trace here. The new-and-improved assertion message will provide more info.

This hasn't recurred in almost 3 months, so closing.
