typescript issue

error: TS2345 [ERROR]: Argument of type ‘{ depth: number; sorted: boolean; trailingComma: boolean; compact: boolean; iterableLimit: number; }’ is not assignable to parameter of type ‘InspectOptions’. Object literal may only specify known properties, and ‘sorted’ does not exist in type ‘InspectOptions’. sorted: true, ~~~~~~~~~~~~ at https://deno.land/std@0.61.0/testing/asserts.ts:26:9

was trying out a basic example

import { Application, Router } from "https://deno.land/x/oak/mod.ts";

const app = new Application();
const router = new Router();

app.use(router.routes());
app.listen({ port: 80 });

The main branch only supports Deno 1.2.0. What version of Deno are you using?

Upgraded to 1.2.0 and now it works as expected, but the console now says

Check file:///app/index.ts.js

in red (formatted as error). is this normal?
