Seems like res does not have the status function. Are you using expressjs? — user2258152
kk so what is the router object or where is it coming from ? — user2258152
import Router from "koa-router"; const router = new Router(); — MHT

Koa router does not return (req, res) but a context instead
https://github.com/ZijianHe/koa-router#router-

router.get('/', (ctx, next) => {
  ctx.res.statusCode = 200
  ctx.body = 'your json data'
})
