Поэтому я уже около трех дней пытаюсь реализовать загрузку изображений в корзину backblaze b2. Я боролся с получением данных, но, наверное, получаю ошибку об отказе в подключении. Он возвращает код ошибки 504, и я попытался исправить это, отправив только изображение, не преобразуя его в данные base64. Я мало что понимаю в данных base64, поэтому я думаю, что ошибка может быть вызвана данными base64. У меня также нет большого опыта работы с backblaze-b2, и я не так давно нашел пакет npm «backblaze-b2». Вот код:

 const B2 = require('backblaze-b2'); const fs = require('fs');  export const uploadImage = async (req, res) =gt; {  try {  const b2 = new B2({  accountId: process.env.BACKBLAZE_ACCOUNT_ID,  applicationKey: process.env.BACKBLAZE_APPLICATION_MASTER_KEY,  });   await b2.authorize();   // console.log(req.body);   const { image } = req.body;   if (!image) return res.status(400).send('No image found!');   // prepare the image  const base64Data = new Buffer.from(  image.replace(/^data:image/w ;base64,/,""),  'base64'  );   const handleImage = async () =gt; {  try {  let uploadUrl = await b2.getUploadUrl({  bucketId: process.env.BACKBLAZE_BUCKET_ID,  });   // console.log('Is this not working?', uploadUrl);   const data = b2.uploadFile({  uploadUrl: uploadUrl.data.bucketId,  uploadAuthToken: uploadUrl.data.authorizationToken,  fileName: 'Pepe', //lt;-- TODO: Fix later  data: base64Data, // lt;-- Figure out what to pass in  onUploadProgress: (e) =gt; null,  });   console.log(data);  res.send(data);  } catch (err) {  console.log('Bucket error or something: ', err);  }  };   handleImage();   } catch (err) {  console.log(err);  } };  

Вот консоль:
