Invariant Violation: Text strings must be rendered within a Text component

Question

I am trying to add my CardsSection component into my Card component however I keep getting this error about a Text Violation but I'm not even using any Text within my Tournament, Card, or CardSection .js files. I don't see why I'm getting this error. Can someone tell me what to do and why?

Tournament.js

import React from "react";
import { View, Text, Image, ScrollView } from "react-native";
import { Card, Button, Spinner, CardSection } from "../common";

class Tournaments extends React.Component {
  static navigationOptions = {
    tabBarLabel: "Tournaments"
  };
  render() {
    return (
      <View style={styles.containerStyle}>
        <Card>
          <View style={styles.logoContainer}>
            <Image
              style={styles.logo}
              source={require("../../Images/ShoeJackCityLogo.png")}
            />
          </View>
          <View style={styles.formContainer} />
        </Card>
        <ScrollView horizontal>
          <Card>
            <View style={{ flex: 1, flexDirection: "row" }}>
              <CardSection>
                <Image
                  style={styles.product}
                  source={require("../../Images/aj_4_toro.png")}
                />
              </CardSection>
              <CardSection>
                <Image
                  style={styles.product}
                  source={require("../../Images/aj_4_toro.png")}
                />
              </CardSection>
              <CardSection>
                <Image
                  style={styles.product}
                  source={require("../../Images/aj_4_toro.png")}
                />
              </CardSection>
            </View>
          </Card>
        </ScrollView>
      </View>
    );
  }
}
const styles = {
  containerStyle: {
    flex: 1,
    backgroundColor: "#F13C20",
    paddingBottom: 20
  },
  logoContainer: {
    alignItems: "center",
    flexGrow: 1,
    justifyContent: "flex-start",
    paddingBottom: 15
  },
  logo: {
    paddingTop: 15,
    width: 50,
    height: 50
  },
  product: {
    width: 100,
    height: 100,
    paddingBottom: 15,
    marginRight: 50
  }
};
export default Tournaments;

CardSection.js

import React from 'react';
import { View } from 'react-native';

const CardSection = (props) => (
    <View style={styles.containerStyle}>
    {props.children};
    </View>
  );

const styles = {
  containerStyle: {
    borderBottomWidth: 1,
    padding: 5,
    backgroundColor: 'white',
    justifyContent: 'flex-start',
    flexDirection: 'row',
    borderColor: '#ddd',
    position: 'relative'
  }
};

export { CardSection };

Card.js

import React from 'react';
import { View } from 'react-native';

const Card = (props) => (
    <View style={styles.containerStyle}>
      {props.children}
    </View>
  );

const styles = {
  containerStyle: {
    borderBottomWidth: 0,
    shadowColor: '#000',
    shadowOffset: { width: 0, height: 2 },
    shadowOpacity: 0.1,
    shadowRadius: 2,
    elevation: 1,
    marginLeft: 5,
    marginRight: 5,
    marginTop: 30,
}
};

export { Card };

You have a semicolon concatenated right after your children in CardSection component. This semicolon is interpreted as text and since every text must be within a <Text> component, the error is thrown.

To fix the issue, simply change

const CardSection = (props) => (
  <View style={styles.containerStyle}>
    {props.children};
  </View>
);

to

const CardSection = (props) => (
  <View style={styles.containerStyle}>
    {props.children}
  </View>
);
