Even after void prepare, any env var accessed via c.env in a handler is typed as unknown despite being declared in env.ts.

TS2345: Argument of type 'unknown' is not assignable to parameter of type 'string'.

The cause seems to be the generated .void/env.d.ts:

type _VoidEnvShape = _VoidEnvSchema extends { default: infer D } ? D : ...;

declare module "void/handler" {
 interface CloudBindings extends _VoidEnvShape {}
}

Note: this surfaces only when typeAware and typeCheck are enabled in the vite-plus lint options.

The workaround i've used:

import type { CloudBindings } from "void/handler";

declare module "void/handler" {
 interface CloudBindings {
 API_SECRET: string;
 }
}
