How can they be configured in server actions? ```ts "use server"; import { revalidatePath } from "next/cache"; import { db } from "~/db"; import { presses } from "~/db/schema"; export const increment = async () => { console.log("yo"); await db.insert(presses).values({}); revalidatePath("/"); }; export const config = { runtime: "edge", regions: ["iad1"], }; ``` I tried this but I get the following error in vercel deployment... ``` Error: x Only async functions are allowed to be exported in a "use server" file. ,-[/vercel/path0/src/app/action.ts:10:1] 10 | revalidatePath("/"); 11 | }; 12 | 13 | ,-> export const config = { 14 | | runtime: "edge", 15 | | regions: ["iad1"], 16 | `-> }; `---- ```
