我收到以下提到的错误。基本配置如下： 我已将文件上传到服务器上，我想下载它们，但收到这些错误时，我向 /api/files/delete/${fileId} 调用了 POST 请求，该请求应该调用路由并返回文件发送到浏览器，而不是使用网格相关模块获取错误。

MONGODB_CONNECTION_STRING = mongodb://localhost:27017/Cstore

Db structure={Cstore:{uploads.files,uploads.chunks,users}}

On requesting POST         axios.post(`/api/files/delete/${fileId}`)

This is server.js

      app.get('/image/:filename', (req, res) => {
    gfs.files.findOne({ 
      _id: mongoose.Types.ObjectId(req.params.filename)
      // filename: req.params.filename.toString()
    }, (err, file) => {
      // Check if file
      if (!file || file.length === 0) {
        console.log("not found")
        return res.status(404).json({
