const localEnvFilePath = context.amplify.pathManager.getLocalEnvFilePath();
    const localEnvInfo = context.amplify.readJsonFile(localEnvFilePath);
    const storageParams = context.amplify.readJsonFile(parametersFilePath);
    this.bucketName = `${storageParams.bucketName}-${localEnvInfo.envName}`;
    const route = path.join('/', this.bucketName);

    let localDirS3 = this.createLocalStorage(context, `${storageParams.bucketName}`);

    try {
