Cannot read properties of null ('reading update')

/* Update an article. */
router.post('/:id/edit', asyncHandler(async (req, res) => {
  const article = await Article.findByPk(req.params.id);
  await article.update(req.body)
  res.redirect("/articles/" + article.id);
  }));

It's throwing "Cannot read properties of null ('reading update')"

Hi Isa Nolla,

Looking at the code snippet you've shared everything should be working. I tried your code in the finished project files and it's working perfectly on my end. If you're still getting an error there might be something wrong elsewhere in your code. If that is the case please share a snapshot of your workspace and we'd be happy to have another look! 😄

I'm using vs code. Is there a way to snapshot that?
