Why is the first element of createWriteStream not added?

Question

Node.js

I want to add files to server like this

uploadFiles: async (_, { files }) => {
      const x = await Promise.all(files);
      for (const [key, value] of x.entries()) {
        const { createReadStream, filename } = value;
        brduj.push(filename);
        createReadStream().pipe(
          createWriteStream(path.join(__dirname, "../images", filename))
        );
      }
    }

but always the first element is not added. I do not understand why. How can this be fixed?
