Thank you for the excellent blog!

I tried implementing the hooks.server.ts in Svelte and get an error:

Argument of type 'Handle' is not assignable to parameter of type 'SvelteKitAuthConfig | ((event: RequestEvent>, string | null>) => PromiseLike)'. Type 'Handle' is not assignable to type '(event: RequestEvent>, string | null>) => PromiseLike'. Types of parameters 'input' and 'event' are incompatible.

I installed the dependencies and put the file in the /src folder. Is there something else I need to do to "satisfy" the Handle?

Thanks, Neil

Hello [Neil Moses](https://hashnode.com/@ndmoses) Thanks for the feedback. Now regarding the query you had, can you compare your code with the one in this GitHub repo - [github.com/aakash14goplani/SvelteKitAuth](https://github.com/aakash14goplani/SvelteKitAuth) I believe that the file placement or a missing dependency is causing this problem
