:::caution[Deprecated] This error was removed in Astro 5.7, when the Sessions feature stopped being experimental. :::

SessionWithoutSupportedAdapterOutputError: Sessions require an adapter that supports server output. The adapter must set "server" in the buildOutput adapter feature.

What went wrong?

Your adapter must support server output to use sessions.
