title: Nest js upload is not saving file
body: <p>I'm following the <code>nestjs</code> documentation for <a href="https://docs.nestjs.com/techniques/file-upload" rel="nofollow noreferrer">File upload</a>, my endpoint is getting the file, but the file is not stored.</p>
  <p>I'm using the same configuration than NesJS</p>
  <pre><code>@Post('upload')
  @UseInterceptors(FileInterceptor('file'))
  uploadFile(@UploadedFile() file) {
    console.log(file);
  }
  </code></pre>
  <p>My <code>app.module</code> file, I added the import for:</p>
  <pre><code>MulterModule.register({
        dest: './uploads'
      })
  </code></pre>
  <p>But the file is not stored in the directory <code>uploads</code>. The complete log is:</p>
  <pre><code>undefined
  {
    fieldname: 'file',
    originalname: 'nopornimage.png',
    encoding: '7bit',
    mimetype: 'image/png',
    buffer: &lt;Buffer 89 50 4e 47 0d 0a 1a 04 d00 01 73 52 47 42 00 ae ce 04 ... 20087 more bytes&gt;,
    size: 20137
  }
  </code></pre>
  <p>(Yes, including the <code>undefined</code>)</p>
  <p>What am I doing wrong?</p>
