We all know mistakes can and will happen. Here’s an easy 404 fix.
With AEM cloud, any AEM instances are updated automatically and you always get the latest features right away. Ideally, updates happen seamlessly. Sometimes, you’ve developed a feature that Adobe, it its effort to be efficient, ends up breaking. Oops!
But when you anticipate that mistakes will inevitably happen, you’ll be better prepared to address the issue before it becomes a pain point for your team, or worse, for your customers. Customizing a 404 error handler is a simple way to ensure that a user friendly error page appears instead of confusing code or unhelpful text.

This happened to us recently. We use a feature to customize our 404 error handler, and it’s something we recommend to all our clients as well. When our 404 error handler stopped working, we investigated what went wrong. Turned out the Apache Sling project had introduced a bug. We reported it to the project and they quickly patched it. The problem stemmed from the length of time it was taking AEM to pick up the fix.
We needed a workaround, which was to turn the 404 error into a user-friendly page that helps provide context or an explanation of what went wrong. It’s important to monitor your site regularly to ensure that when something stops working, there’s a quick, easy, and friendly way to address the issue.
