'Cannot read property aID of undefined'

On my put request, a 500 error is thrown 'Cannot read property aID of undefined'

Req URL: localhost:3000/questions/9/answers/33/

This is my route for the request

router.put('/:qID/answers/:aID', (res, req) => {
    res.json({ 
        response: `You sent me a PUT request to /answers/${req.params.aID}` ,
        questionId: req.params.qID,
        answerId: req.params.aID,
        body: req.body
    });
});

EDIT: I had placed (res, req) => the wrong way around, changing this to (req, res) => obviously fixes the issue, doh.
