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

The experimental.session flag was set to true, but no storage was configured. Either configure the storage manually or use an adapter that provides session storage.

What went wrong?

Thrown when session storage is enabled but not configured.
