No form submission with next js


I followed the guidance from [Support Guide] Form problems, form debugging, 404 when submitting but my forms do not work.

  1. It is a pure HTML form built from a next js
  2. It is accessible here:
  3. The corresponding code is here: at 7e5685632edd90fa3e692114e69ef8867bcba7de · MieuxVoter/ · GitHub
  4. The forms appear in my dashboard Netlify App but no submission appears in spam/not spam.
  5. I tried to add a thank-you message: the form got redirected there, but without recording my submission.


Hi @guhur,

Your problem is covered in the guide you’ve linked above, specifically, it’s this section here:

Point 2 under that heading.
