Why doesn't multer middleware run my route in express?

Question

Node.js

I am sure that the problem is in async await, but I don’t understand how to get rid of it, the middleware reaches UploadFileCtrl.uploads and after that there is a cyclic loading of images in the browser (pending), that is, after console.log the code is not executed,
I will be very grateful for the answer

app.post('/photos/upload', (req, res) => {
  upload(req, res, (err: any) => {
    if (err) return res.send({ error: 'invalid_file' })
    console.log('hello from here')

    UploadFileCtrl.uploads
  })
})

class UploadFileController {
  async uploads(req: express.Request, res: express.Response): Promise<void> {
    const files: any = req.files
    if (files) {
      const urls = []
      for (const file of files) {
        const result = await uploadFromBuffer(file.buffer, 'Tweets')
        urls.push(result)
      }
      res.status(200).json({
        message: 'images uploaded successfully',
        data: urls,
      })
    } else {
      res.status(204).json({
        err: 'Empty',
      })
    }
  }
}

export const uploadFromBuffer = (buffer: Buffer, folder: string) => {
  return new Promise((resolve, reject) => {
    const stream = cloudinary.uploader.upload_stream(
      {
        folder,
      },
      (error: any, result: any) => {
        console.log(error, result)
        if (result) {
          resolve({
            url: result.url,
            size: Math.round(result.bytes / 1024),
            height: result.height,
            width: result.width,
          })
        } else {
          reject(error)
        }
      }
    )

    streamifier.createReadStream(buffer).pipe(stream)
  })
}
