error status code possibly not defined???

here is my code

const error = new Error('MIMIMIIIIIII *voicecrack');

//cut out lines of code

app.use((req, res, next)=>{
    res.status(error.status);
    next(error);
})

app.use((err, req, res, next)=>{
    res.render('error', error);
})

i checked the chrome development console and it said this:

RangeError [ERR_HTTP_INVALID_STATUS_CODE]: Invalid status code: undefined
    at ServerResponse.writeHead (node:_http_server:352:11)
    at ServerResponse._implicitHeader (node:_http_server:338:8)
    at write_ (node:_http_outgoing:945:9)
    at ServerResponse.end (node:_http_outgoing:1056:5)
    at ServerResponse.send (C:\Users\User\Desktop\life\node_modules\express\lib\response.js:232:10)
    at done (C:\Users\User\Desktop\life\node_modules\express\lib\response.js:1045:10)
    at exports.renderFile (C:\Users\User\Desktop\life\node_modules\pug\lib\index.js:448:12)
    at exports.__express [as engine] (C:\Users\User\Desktop\life\node_modules\pug\lib\index.js:493:11)
    at View.render (C:\Users\User\Desktop\life\node_modules\express\lib\view.js:135:8)
    at tryRender (C:\Users\User\Desktop\life\node_modules\express\lib\application.js:657:10)

and i am assuming that i didn't define the status code of the variable 'error' if that's the case, then i don't really know how to define it.

i tried to run the error handler line by line using the vs code debug feature but as of now i couldn't get my web server to load for some reason, maybe it is slow internet

Hey jason limmm 👋

When you're creating a new Error object the status code property is not automatically being set. You'll have to explicit set it: 

error.status = 500

Of course you'll want to update that to use the appropriate status code for the type of error you're handling 🙂
