React Native retrieving API data source.uri should not be an empty string - react-native

Question

I am trying to retrieve data from an API (https://developers.zomato.com/documentation) and get title of restaurants and an image with it. However when I try to load an image I get a warning source.uri should not be an empty string.
Here is my code as it stands:
async componentDidMount() {
let id = this.props.navigation.state.params.category
let result;
try {
result = await axios.request({
method: 'get',
url: `https://developers.zomato.com/api/v2.1/search?category=${id}`,
headers: {
'Content-Type': 'application/json',
'user-key': "a31bd76da32396a27b6906bf0ca707a2",
},
})
} catch (err) {
err => console.log(err)
}
this.setState({
isLoading: false,
data: result.data.restaurants
})
}
render() {
return (
<View>
{
this.state.isLoading ?
<View style={{ flex: 1, padding: 20 }}>
<ActivityIndicator style={{color:'red'}} />
</View> :
(
this.state.data.length == 0 ?
<View style={{ flex: 1, padding: 20 }}>
<Text style={{ color: '#000', fontWeight: 'bold' }}>No restaurants from selected category</Text>
</View> :
<FlatList
style={{ marginBottom: 80 }}
keyExtractor={item => item.id}
data={this.state.data}
renderItem={({ item }) =>
<TouchableHighlight onPress={()=> console.log(item.restaurant.thumb)}>
<Card image={item.restaurant.thumb} style={styles.container}>
<Image resizeMode='contain' source={{ uri: item.restaurant.thumb }}/>
<Text style={{color:'#000',fontWeight:'bold'}}>{item.restaurant.name} </Text>
</Card>
</TouchableHighlight>
}
/>
)
}
</View>
);
}
as you can see when I touch the any of the cards I am console logging the link of the image uri and it shows up perfectly. Why is that when the app loads the images they are empty strings yet when I load it though console log the link shows up perfectly?
I am using axios to load my API
here is an expo snack link: https://snack.expo.io/r1XTaw4JU

Answer 1

So i got 2 issues, one is in the card component you were not providing the uri properly it should be image={{uri:item.restaurant.thumb}} and secondly for newyork your entity id must be
To search for 'Italian' restaurants in 'Manhattan, New York City',
set cuisines = 55, entity_id = 94741 and entity_type = zone
Its as per zomato docs,so do check out that. and find expo link : expo-snack
