Reproduction

https://stackblitz.com/edit/github-w6rohg?file=nuxt.config.ts

Builds work locally, deployment to Vercel does not.

Describe the bug

URL's are correctly generated using the baseURL: /docs/logo.svg, however they are still served from the root directory as opposed to the base URL, resulting in a 404. The same applies to /docs/_nuxt/ assets.

Works fine with a local build, but not when deployed on Vercel.

Would you see if you can reproduce this in pure Nitro (reproduction sandbox), and if so, raise there? 🙏

any news here? facing the same problem serving over docker container on a docker-swarm network domain and app in a sub-path like:

my-domain.com/my-nuxt-app-1
my-domain.com/my-nuxt-app-2
my-domain.com/my-nuxt-app-3

[JohannesPichlerSTRABAG]

We found the solution in our case. Might be related to that.
The nitro server itself expects to run and serve the app on a sub-path, which works fine.
If the Kubernetes ingress is not set to have its base rewrite also on the sub-path, the two configurations do not match.
For us, setting the rewrite target to the subfolder of the running app did the trick to serve correctly.

would be great to add an additional option to the nuxt config to handle situations, where we can not access configurations, to set the deployments to root and then do not redirect the frontend to root, but stay on the sub-path
