Migrate from express 4 to 5

How du you migrate this when switchen from express 4 to 5:
app.use(cors());
app.options('*', cors()); // include before other routes

It gives a
/xxx/node_modules/path-to-regexp/dist/index.js:73 throw new TypeError(Missing parameter name at ${i}: ${DEBUG_URL}); ^ TypeError: Missing parameter name at 1: https://git.new/pathToRegexpError

```js app.options('/*paramName', /* handler */); // All routes, except / app.options('/{*paramName}', /* handler */); // All routes including / ``` You can replace `paramName` with anything as long as it is a valid JS identifier. See: - https://git.new/pathToRegexpError (yes, that's the link from the error message) - #5936 - #6111 - [5.x migration guide](https://expressjs.com/en/guide/migrating-5.html)

So now you need to be more explicit - where as the '*' was more like a wildcard matching everyting - right?

[krzysdz]

* now matches at least one character (in 4.x it would match 0 or more) and requires a parameter name like :.
