Comicly poor CMS validation

I’ve got an editor trying to edit CMS content and it kept failing. I then tried it from my account and we kept getting a vague ‘validation error’. The error was awful for a few reasons that I feel the most basic products on earth can handle:

  1. does not tell you what the error is (what on earth?! - it is 2024!!)
  2. doesn’t even let you edit the page and try to save again - you have to refresh the page, lose all your changes and try again
  3. because I have a bit of experience, I used chrome dev tools to inspected the console and see there is a basic error payload that made it clear the problem was with the date. Though no user friendly error text, of course.
  4. turns out we were using non-US data formats (DD/MM/YYY) instead of the format Webflow wanted (MM/DD/YYYY). Once we fixed it, saved just fine.

But I’m just shocked by the lack of basic website development 101 - gracefully handle errors and communicate clearly with the user…is it just me or is this an indicator of the general build quality?
