Known issues
Here are some known bugs and issues with Cloudflare Pages:
 Builds and deployment
- GitHub and GitLab are currently the only supported platforms for automatic CI/CD builds. Direct Upload allows you to integrate your own build platform or upload from your local computer. 
- Monorepos or repositories with multiple codebases/applications currently cannot use the automatic GitHub/GitLab integration to build multiple sites from the same repository. However, Direct Upload can be used to upload a monorepo as separate Pages projects from your own computer. 
- Incremental builds are currently not supported in Cloudflare Pages. 
- Uploading a - /functionsdirectory through the dashboard’s Direct Upload option does not work (refer to Using Functions in Direct Upload).
- Commits/PRs from forked repositories will not create a preview. Support for this will come in the future. 
 Git configuration
- After you have selected a GitHub/GitLab repository for your Pages application, it cannot be changed. Delete your Pages project and create a new one pointing at a different repository if you need to update it.
 Build configuration
- *.pages.devsubdomains currently cannot be changed. If you need to change your- *.pages.devsubdomain, delete your project and create a new one.
- Hugo builds automatically run an old version. To run the latest version of Hugo (for example, - 0.101.0), you will need to set an environment variable. Set- HUGO_VERSIONto- 0.101.0or the Hugo version of your choice.
- By default, Cloudflare uses Node - 12.18.0in the Pages build environment. If you need to use a newer Node version, refer to the Build configuration page for configuration options.
- For users migrating from Netlify, Cloudflare does not support Netlify’s Forms feature. Pages Functions are available as an equivalent to Netlify’s Serverless Functions. 
 Custom Domains
- It is currently not possible to add a custom domain with - a wildcard, for example, *.domain.com.
- a Worker already routed on that domain.
 
- a wildcard, for example, 
- It is currently not possible to add a custom domain with a Cloudflare Access policy already enabled on that domain. 
- Cloudflare’s Load Balancer does not work with - *.pages.devprojects; an- Error 1000: DNS points to prohibited IPwill appear.
- When adding a custom domain, the domain will not verify if Cloudflare cannot validate a request for an SSL certificate on that hostname. In order for the SSL to validate, ensure Cloudflare Access or a Cloudflare Worker is allowing requests to the validation path: - http://{domain_name}/.well-known/acme-challenge/*.
- Advanced Certificates cannot be used with Cloudflare Pages due to Cloudflare for SaaS’s certificate prioritization. 
 Pages Functions
- Functions does not currently support adding/removing polyfills, so your bundler (for example, webpack) may not run. 
- passThroughOnException()is not currently available for Advanced Mode Pages Functions (Pages Functions which use an- _worker.jsfile).
- passThroughOnException()is not currently as resilient as it is in Workers. We currently wrap Pages Functions code in a- try/- catchblock and fallback to calling- env.ASSETS.fetch(). This means that any critical failures (such as exceeding CPU time or exceeding memory) may still throw an error.
Enable Access on your *.pages.dev domain
If you would like to enable Cloudflare Access] for your preview deployments and your *.pages.dev domain, you must:
- Log in to Cloudflare dashboard.
- From Account Home, select Workers & Pages.
- In Overview, select your Pages project.
- Go to Settings > Enable access policy.
- Select Edit on the Access policy created for your preview deployments.
- In Edit, go to Overview.
- In the Subdomain field, delete the wildcard (*) and select Save application. You may need to change the Application name at this step to avoid an error.
At this step, your *.pages.dev domain has been secured behind Access. To resecure your preview deployments:
- Go back to your Pages project > Settings > General > and reselect Enable access policy.
- Review that two Access policies, one for your *.pages.devdomain and one for your preview deployments (*.<YOUR_SITE>.pages.dev), have been created.
If you have a custom domain and protected your *.pages.dev domain behind Access, you must:
- Select Add an application > Self hosted in Cloudflare Zero Trust.
- Input an Application name and select your custom domain from the Domain dropdown menu.
- Select Next and configure your access rules to define who can reach the Access authentication page.
- Select Add application.
If you have an issue that you do not see listed, let the team know in the Cloudflare Workers Discord. Get your invite at discord.gg/cloudflaredev, and share your bug report in the #pages-general channel.
