React Native interpolate maximum call stack size exceeded

Question

I'm kinda new to RN and I'm having a hard time tracking down a "Maximum stack call exceeded". I understand that the error is related to some kind of infinite loop going on in my code but I can't find it.

Code

EventScreen:

import Animated, { interpolate, Extrapolate, Value } from "react-native-reanimated";

export default class EventScreen extends React.Component<EventScreenProps, EventScreenState> {
  render() {
    const animatedValueRef = new Value(0);
    const height = interpolate(animatedValueRef, {
      inputRange: [-MAX_HEADER_HEIGHT, 0],
      outputRange: [0, MAX_HEADER_HEIGHT],
      extrapolate: Extrapolate.CLAMP
    });

    return (
      <SafeAreaView style={style.screenContainer}>
        <CollapsibleHeaderBar backgroundImage={event?.flyer} animatedValueRef={animatedValueRef} >
          <TouchableOpacity style={style.shareButton}>
            <Icon2 name="ios-share-alt" size={24} style={style.shareButtonIcon} />
            <Text style={style.shareButtonText}>CONDIVIDI</Text>
          </TouchableOpacity>
        </CollapsibleHeaderBar>
        <Animated.ScrollView
          style={style.flexOne}
          onScroll={onScroll({ y: animatedValueRef })}
          showsVerticalScrollIndicator={false}
          scrollEventThrottle={1}>
          <View style={style.cover}>
            <Animated.View style={[style.gradient, { height }]} />
            <LinearGradient style={style.flexOne} colors={["transparent", "rgba(0, 0, 0, 0.2)", Colors.appBackgroundColorValue]} />
          </View>
          ...
        </Animated.ScrollView>
        ...
      </SafeAreaView>
    )
  }
}

CollapsibleHeaderBar:

import { interpolate, Extrapolate, color } from "react-native-reanimated";

export default class CollapsibleHeaderBar extends React.PureComponent<CollapsibleHeaderBarProps> {

  render() {
    const { backgroundImage, collapsedText, animatedValueRef } = this.props;
    const opacity = interpolate(animatedValueRef, {
      inputRange: [-50, 0, HEADER_DELTA + 60],
      outputRange: [0, 0, 1],
      extrapolate: Extrapolate.CLAMP,
    });
    const textOpacity = interpolate(animatedValueRef, {
      inputRange: [HEADER_DELTA - 30, HEADER_DELTA],
      outputRange: [0, 1],
      extrapolate: Extrapolate.CLAMP,
    });
    const backgroundColor = color(18, 18, 18, interpolate(animatedValueRef, {
      inputRange: [MIN_HEADER_HEIGHT, HEADER_DELTA - 30],
      outputRange: [0.3, 1],
      extrapolate: Extrapolate.CLAMP,
    }));
    const borderBottomColor = color(65, 65, 65, interpolate(animatedValueRef, {
      inputRange: [MIN_HEADER_HEIGHT, HEADER_DELTA - 30],
      outputRange: [0.3, 1],
      extrapolate: Extrapolate.CLAMP,
    }));
    return (
      <View>
        <Animated.View style={style.headerContainer}>
          <Image style={style.backgroundImage} source={{ uri: backgroundImage }} />
          <Animated.View style={[style.barOverlay, { opacity }]} />
        </Animated.View>
        <Animated.View style={[style.barAnimation, { backgroundColor, borderBottomColor }]}>
          <View style={style.barContainer}>
            <TouchableOpacity onPress={this._onBackPressed}>
              <Icon name="chevron-left" size={24} style={style.goBackIcon} />
            </TouchableOpacity>
            <Animated.Text style={{ opacity: textOpacity }}>{collapsedText}</Animated.Text>
          </View>
          {this.props.children}
        </Animated.View>
      </View>
    );
  }
}

Error

What I've understood so far

• The error seems to be related to me passing a react-native-reanimated Value from the EventScreen to the CollapsibleHeaderBar
• The react-native-reanimated Value by itself is working since it's used on the EventScreen (see the height interpolation)
• The problem seems also to be related to the interpolation on the CollapsibleHeaderBar
• Commenting out the CollapsibleHeaderBar from the EventScreen solves the problem
• Commenting out the styles with the interpolation components in the CollapsibleHeaderBar also solves the problem
• The code apparently stops working after the render phase of the CollapsibleHeaderBar
• I've seen other examples of this kind of cross-components animations, so theoretically it should be possible
• The onScroll event never gets triggered (apparently the error occurs before)
• Each render function is called only once, so the loop is not there

Thanks for your help.

Answer 1

I've solved the problem. The Animated I was importing on the CollapsibleHeaderBar was not from the same library (reanimated) but was from react-native. Changing that fixed it.

I've also learned that you have to put the animated value inside the state, otherwise the animation won't work properly.
