🐛LaunchData is being ignored

[grahamyesfit]

What were you trying to do?

I have created a Lens using Snapchat's dynamic lens example as a starting point.

I tested the Lens in Lens Studio with a fallback datasource and the Lens was correctly showing the values.

I published the Lens and I'm viewing it in our App.

Reproduceable Code

//JavaScript code 

	const initialLaunchData = { 
		challenge: 'Return to Oz',
		duration: '... in 13 Days', 
		stats: ["22 Workouts", "13K calories burned", "30 miles"], 
		date: [2023, 12, 14]  
	};

    return (
        <>
            <CameraKit
                ref={ref}
                style={styles.container}
                isActive={active}
                initialCameraFacing="front"
                initialLens={{
                    id: route?.params?.lensId,
                    launchData: initialLaunchData,
                }}
                zoom={zoom}
                focus={focus}
                preset="hd-1280x720"
                lensGroups={[cameraKitSettings.lensGroupId]}
                onInitialized={() => {
                    console.log('onInitialized');
                }}
                onLensChanged={(_event) => {
                    // console.log(event);
                }}
                onPhotoTaken={(picture) => {
                    console.log({ picture });
                    navigation.navigate('SnapchatPreviewScreen', {
                        type: Enums.PREVIEW_TYPES.PHOTO,
                        path: picture.path,
                    });
                }}
                onVideoRecordingFinished={(video) => {
                    console.log({ video });
                    setIsVideoRecording(false);
                    navigation.navigate('SnapchatPreviewScreen', {
                        type: Enums.PREVIEW_TYPES.VIDEO,
                        path: video.path,
                    });
                }}
                onError={(error) => {
                    console.log('onError', error);
                }}

        script.dateText.text = global.localizationSystem.getDateFormatted(new Date(date[0], date[1] -1, date[2]));      
    } else {
        print("Error: Incorrect date passed in, should be [year, month, day]. Today's date will be used instead");
        script.dateText.text = global.localizationSystem.getDateFormatted(new Date());
    }
    
}


if(getData()) { 
    populateFields();
} else {
    print("Failed to get Data");

What happened instead?

The correct Lens is shown but the hardcoded values for the fields are shown, not the launchData values that were passed in.

Hello @grahamyesfit,

I was the sole contributor to this repository. Unfortunately, due to a company layoff, I have left. As a result, there is no one maintaining this library anymore.

Nevertheless, I intend to address this issue at the appropriate time. It appears to be a straightforward problem to fix.
