I'm using version 1.0.1 of Motion Layout for Jetpack Compose alongside with compose bom 2024.02.01, material3 and a JSON5 motion scene, and when i try to do a simple use case such animating Text() font size, the app crashes with the next error message:

java.lang.IllegalArgumentException: no paragraph androidx.compose.foundation.text.modifiers.TextStringSimpleNode.draw(TextStringSimpleNode.kt:390)

I followed the example in: https://github.com/androidx/constraintlayout/wiki/Compose-MotionLayout-JSON-Syntax

custom: {
background: '#0000FF',
textColor: '#FFFFFF',
textSize: 12
}

var properties = motionProperties("a")
Text(text = "Hello", modifier = Modifier
.layoutId(properties.value.id())
.background(properties.value.color("background"))
,color = properties.value.color("textColor")
,fontSize = properties.value.fontSize("textSize")
)

I think it has something to do with the implementation of the new Modifier.Node() method for Text composables drawing/rendering
