# 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.
|
|
}
|
|
}
|
|
```
