# E4012

Nuxt could not parse the response returned when rendering a server component (island). This usually means the server component endpoint returned something other than the expected island payload, such as an error page or malformed HTML.

## Resolution

Check the server component for errors that would prevent it from rendering, and confirm the island endpoint returns a valid response. Inspect the network response for the island request to see what the server actually returned.
