# How to create custom error pages in Bubble.io: Step-by-Step Guide - Tool: Bubble - Difficulty: Beginner - Time required: 15-20 min - Compatibility: All Bubble plans - Last updated: March 2026 ## TL;DR Custom error pages in Bubble replace the default 404 page with branded, helpful pages that guide lost users back to your content. This tutorial covers designing a custom 404 page, handling invalid dynamic page URLs gracefully, redirecting from deleted or moved pages, and creating a consistent error experience that matches your app's branding. ## Overview: Creating Custom Error Pages in Bubble This tutorial shows you how to create helpful, branded error pages in your Bubble app. You will customize the built-in 404 page, handle scenarios where dynamic pages receive invalid data, and set up redirects from old or deleted page URLs. ## Before you start - A Bubble app with at least a few pages - Basic familiarity with Bubble page settings and workflows - Understanding of dynamic pages and URL slugs in Bubble ## Step-by-step guide ### 1. Customize the built-in 404 page Every Bubble app includes a default '404' page that displays when a user visits a URL that does not match any page. Navigate to this page in the Bubble editor (it appears in your pages list as '404'). Design it to match your app's branding — add your logo, a friendly error message like 'This page does not exist', a search bar, and navigation links to popular pages. Include a prominent button linking back to your homepage. Use your app's Color Variables and Styles for consistency. **Expected result:** Your 404 page matches your app's branding and provides helpful navigation options for lost users. ### 2. Handle invalid dynamic page URLs Dynamic pages (pages that load content based on a URL slug or ID) can fail when the URL contains an invalid or deleted record ID. Add a 'Page is loaded' workflow on your dynamic page with the condition: Current Page's data thing is empty. When this condition is true, redirect the user to the 404 page or show an inline error message. Use Element Actions → Show on an error group that says 'This content is no longer available' and hide the main content group. This prevents broken pages from showing empty templates. > Pro tip: Use 'Go to page 404' instead of showing inline errors if you want a consistent error experience across all pages. **Expected result:** Dynamic pages with invalid URLs display a helpful error message instead of an empty template. ### 3. Set up redirects for moved or deleted content Create a Data Type called Redirect with fields: old_path (text), new_path (text). When you delete or move content that had a public URL, create a Redirect record with the old and new paths. On your 404 page, add a 'Page is loaded' workflow that searches for a Redirect where old_path matches the current page URL. If a match is found, use the 'Open an external website' action to navigate to the new_path. This preserves SEO value from old links and prevents users from hitting dead ends. **Expected result:** Old URLs automatically redirect to new locations, preserving SEO value and user experience. ### 4. Add a search feature to the error page On your 404 page, add a Search Input and a Repeating Group that shows matching pages or content. When the user types in the search input, display results from your main content Data Type (e.g., Posts, Products) filtered by the search text. This turns a dead end into a discovery opportunity. Also add links to your most popular pages — homepage, blog, contact, and any high-traffic sections. Style everything to feel helpful rather than alarming. **Expected result:** Users on the error page can search for content or click popular page links to find what they were looking for. ### 5. Track 404 errors for monitoring Add event tracking to your 404 page to identify broken links and missing content. In the 'Page is loaded' workflow on the 404 page, create an AnalyticsEvent (or a dedicated ErrorLog Data Type) recording the attempted URL (using Get data from page URL), the referring URL, and the timestamp. Review these logs periodically to identify patterns — common 404 URLs may indicate broken links on your site or external sites linking to removed content. Fix these by adding Redirect records or updating the links. **Expected result:** 404 errors are logged for monitoring, helping you identify and fix broken links proactively. ## Complete code example File: `Workflow summary` ```text CUSTOM ERROR PAGES ARCHITECTURE ================================= 404 PAGE DESIGN: - App logo and branding - Friendly message: 'This page does not exist' - Search bar for finding content - Links to popular pages (Home, Blog, Contact) - Back to Homepage button DYNAMIC PAGE ERROR HANDLING: Page is loaded workflow: Condition: Current Page's data thing is empty Actions: → Hide main content group → Show error message group OR → Go to page: 404 REDIRECT SYSTEM: Data Type: Redirect - old_path: text - new_path: text 404 Page workflow: Page is loaded: Search: Do a Search for Redirects where old_path = Get data from page URL (path) If result count > 0: → Open external website: result's new_path 404 ERROR TRACKING: Data Type: ErrorLog - attempted_url: text - referrer: text - timestamp: date 404 Page workflow: Page is loaded: → Create ErrorLog attempted_url = Get data from page URL (full) timestamp = Current date/time ``` ## Common mistakes - **Leaving the default 404 page unbranded** — The default 404 page looks generic and may confuse users into thinking they left your app entirely Fix: Design the 404 page with your branding, logo, colors, and navigation to maintain a consistent experience - **Not handling empty data on dynamic pages** — When a dynamic page receives an invalid ID, it shows an empty template with placeholder text, looking broken rather than intentionally showing an error Fix: Add a Page is loaded workflow that checks if the page data is empty and shows an error message or redirects to the 404 page - **Using hard redirects that create infinite loops** — If a redirect points to another redirected URL, or the 404 page redirects to itself, the browser enters an infinite loop Fix: Always redirect to existing, valid URLs. Add a safeguard that limits redirect chains to one hop. ## Best practices - Design your 404 page with full branding, navigation, and a search feature - Check for empty data on dynamic pages and handle the error gracefully - Maintain a Redirect Data Type for moved or deleted content to preserve SEO value - Track 404 errors to identify and fix broken links proactively - Include links to popular pages on the error page to help users find relevant content - Use friendly, non-technical language in error messages ## Frequently asked questions ### Does Bubble automatically show a 404 page for invalid URLs? Yes. Bubble automatically redirects to the 404 page when a user visits a URL that does not match any page name. However, dynamic pages with invalid data parameters are NOT automatically caught — you need to handle those separately. ### Can I redirect old URLs to new ones in Bubble? Yes. Create a Redirect Data Type with old and new paths. On the 404 page, search for a matching redirect and navigate to the new URL if found. ### How do I track which pages are causing 404 errors? Add a Page is loaded workflow on the 404 page that logs the attempted URL and timestamp to a tracking Data Type. Review this data periodically to find and fix broken links. ### Should I show an inline error or redirect to the 404 page for dynamic pages? If the user was clearly looking for specific content (like a blog post), show an inline error with alternative suggestions. For unknown URLs, redirect to the 404 page. ### Can RapidDev help set up error pages and redirect systems in Bubble? Yes.
