Type error with express

back-end

Why the hell does this give me a type error for string? tips is an array with strings, I am parsing the param id to a number to be used as index.
This is whats shown in the example code given by the teacher.

router.get("/tip/:id", (req: Request, res: Response): void => {
  const id: number = parseInt(req.params.id);
  const tip: string = tips[id - 1];
  res.render("tip", {
    title: "Tip",
    id: id,
    tip: tip,
  });
});

router.get("/tip/:id", (req: Request, res: Response): void => {
  const id: number = parseInt(req.params.id);
  const tip: string = tips[id - 1];
  res.render("tip", {
    title: "Tip",
    id: id,
    tip: tip,
  });
});
