Unable to receive file data

[Turbine1991]

I'm unable to loop through the files at the fastify end.

I've created a simple form with the help of bulma:

<form id="form-upload" action="/upload/submit" method="post">
  <div id="file-js-example" class="file has-name">
    <label class="file-label">
      <input class="file-input" type="file" name="files" id="files">
      <span class="file-cta">
        <span class="file-icon">
          <i class="fas fa-upload"></i>
        </span>
        <span class="file-label">
          Choose a file…
        </span>
      </span>
      <span class="file-name">
        No file uploaded
      </span>
    </label>
  </div>
</form>

Here is the fastify code:

www.fastify.post('/upload/submit', function (req, reply) {
  console.log(req.raw.files); // This returns null
});

I presume that I've done something wrong in creating the HTML form?
Thank you.

If you use the HTML form action to call your backend endpoint, then you probably need to add enctype="multipart/form-data" attribute on it, so the browser knows the request should be sent as multipart and the backend can parse files.
