# errors variable
Puppeteer methods might throw errors if they are unable to fulfill a request. For example, `page.waitForSelector(selector[, options])` might fail if the selector doesn't match any nodes during the given timeframe.
For certain types of errors Puppeteer uses specific error classes. These classes are available via `puppeteer.errors`.
**Signature:**
```typescript
errors: PuppeteerErrors;
```
## Example
An example of handling a timeout error:
```ts
try {
await page.waitForSelector('.foo');
} catch (e) {
if (e instanceof puppeteer.errors.TimeoutError) {
// Do something if this is a timeout.
}
}
```
