          thumbnailFileNames.push(...filenames);
        })
        .on("end", () => {
          resolve(thumbnailFileNames);
        })
        .on("error", (err) => {
          reject(err);
        })
        .screenshots({
          timestamps,
          filename: `${thumbnailFilePattern}-%s.png`,
          folder: '/tmp',
          size: `${width}x${height}`,
