Form submission fails with 404 on a minimal test case

Support

Hello,

My form on site idyllic-selkie-ee34a5.netlify.app is successfully detected and appears in my “Forms” tab.

However, all live submissions result in a 404 error page, and no submission data is ever captured in the dashboard. I am also not receiving email notifications.

I have already performed extensive troubleshooting and have confirmed the following:

  • The thanks.html success page is present at the root of the published deploy.
  • My visible form has all required Netlify attributes: data-netlify="true", a name attribute, action="/thanks.html", and a hidden <input name="form-name">.
  • I have an identical hidden HTML form for the build bots.
  • I have tried deleting the site and re-deploying from scratch.

I am wondering if this is a server-side issue with processing the form submission, even though the form itself is detected correctly. Could you please check the logs for my site to see why the submission is failing?

Thank you.
