# --description--
`catch` is the method used when your promise has been rejected. It is executed immediately after a promise's `reject` method is called. Heres the syntax:

`error` is the argument passed in to the `reject` method.
# --instructions--
Add the `catch` method to your promise. Use `error` as the parameter of its callback function and log `error` to the console.
# --hints--
You should call the `catch` method on the promise.
```js
assert(
__helpers.removeWhiteSpace(code).match(/(makeServerRequest|\))\.catch\(/g)
);
```
Your `catch` method should have a callback function with `error` as its parameter.
```js
assert(errorIsParameter);
```
You should log `error` to the console.
```js
assert(
errorIsParameter &&
__helpers
.removeWhiteSpace(code)
.match(/\.catch\(.*?error.*?console.log\(error\).*?\)/)
);
