Adapter does not support server output.

AdapterSupportOutputMismatch: The ADAPTER_NAME adapter is configured to output a static website, but the project contains server-rendered pages. Please install and configure the appropriate server adapter for your final deployment.

Section titled What went wrong?

The currently configured adapter does not support server-side rendering, which is required for the current project setup.

Depending on your adapter, there may be a different entrypoint to use for server-side rendering. For example, the @astrojs/vercel adapter has a @astrojs/vercel/static entrypoint for static rendering, and a @astrojs/vercel/serverless entrypoint for server-side rendering.
