How to create strongly typed ServerClient with a custom schema?

[crowne]

My codebase is svelte-5 with typescript.
I'm following this guide https://supabase.com/docs/guides/auth/server-side/sveltekit

The problem is that I want to set a custom schema in src/hooks.server.ts

  event.locals.supabase = createServerClient(PUBLIC_SUPABASE_URL, PUBLIC_SUPABASE_ANON_KEY, {
    db: {
            schema: 'myschema'
    },
    cookies: {
      getAll: () => event.cookies.getAll(),
      /**
       * SvelteKit's cookies API requires `path` to be explicitly set in
       * the cookie options. Setting `path` to `/` replicates previous/
       * standard behavior.
       */
      setAll: (cookiesToSet) => {
        cookiesToSet.forEach(({ name, value, options }) => {
          event.cookies.set(name, value, { ...options, path: '/' })
        })
      },
    },
  })

But this clashes with the supabase client definition in src/app.d.ts

    interface Locals {
      supabase: SupabaseClient
      safeGetSession: () => Promise<{ session: Session | null; user: User | null }>
      session: Session | null
      user: User | null
    }

The error that I get is :

Type 'SupabaseClient<any, "myschema", any>' is not assignable to type 'SupabaseClient<any, "public", any>'.
  Type '"myschema"' is not assignable to type '"public"'.
