My code: const fs = require('fs'); const converter = require('./src/index');

const rivFilePath = './riveAnimation.riv'; // Ensure this file exists

try { const buffer = fs.readFileSync(rivFilePath); const animationsData = converter(buffer);

if (animationsData && animationsData.length > 0) {
    animationsData.forEach((anim, index) => {
        const outputFilePath = `./data_rive_${index}.json`;
        fs.writeFile(
            outputFilePath,
            JSON.stringify(anim, null, 2),
