11ty form submit not working

Hi i’m using the following code:

<form name="comments-queue" action="/thanks" method="POST" netlify-honeypot="full-name" data-netlify="true" >
  <p class="honey">
    <input name="path" type="hidden" value="{{ page.url }}">
    <label>Your full name: <input name="full-name"></label>
  </p>
  <p>
    <label for="name">Your name<small>What should I call you?</small></label>
    <input type="text" name="name" id="name">
  </p>
  <p>
    <label for="email">Your email<small>I'll only spam if you check below checkbox!</small></label>
    <input type="email" name="email" id="email">
  </p>
  <p>
    <label for="newsletter">Do you want to receive my newsletter?
    <input type="checkbox" name="newsletter" id="newsletter">
    </label>
  </p>
  <p>
    <label for="comment">Your comment<small>Markdown is fine.</small></label>
    <textarea name="comment" id="comment"></textarea>
  </p>
  <p>
    <button type="submit" class="btn">Submit comment</button>
  </p>
</form>

This actually submits the form, but it redirects to the 404 with URL saying “/thanks” if i then manual refresh the URL it will actually load the page.

My guess it’s more on 11ty side, but does anyone have any experience with this?

Although not directly related, this Support Guide doc might be a worthwhile read!
