Known issues

Here are some known bugs and issues with Cloudflare Pages:

GitHub and GitLab are currently the only supported Source code hosting tools.
Pages currently only supports a single project per repository. Monorepos or repositories with multiple codebases/applications currently cannot deploy more than one project to Pages at a time.
Once you have selected a GitHub repository for your Pages application, it cannot be changed. Remove/delete your Pages project and create a new one pointing at a different repository if you need to update it.
*.pages.dev subdomains currently cannot be changed. If you need to change your *.pages.dev subdomain, delete your project and create a new one.
Hugo builds automatically run an old version. To run the latest version of Hugo (for example, 0.80.0), you will need to set an environment variable. Set HUGO_VERSION to 0.80.0 or the Hugo version of your choice.
By default, Cloudflare uses Node 12.18.0 in 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 and Serverless Functions features.
It is currently not possible to add a custom domain with a wildcard, for example, *.domain.com.
It is currently not possible to add a custom domain with a Worker already routed on that domain.
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.dev projects; an Error 1000: DNS points to prohibited IP will appear.
A GitHub or GitLab account cannot be attached to more than one Cloudflare account.
Functions (beta) does not currently support adding/removing polyfills, so your bundler (for example, Webpack) may not run.
When adding a custom domain, the domain may get stuck verifying due to being unable to validate a request for an SSL 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/pki-validation/*.
