## Protocol.Security.CertificateErrorEvent interface

There is a certificate error. If overriding certificate errors is enabled, then it should be handled with the `handleCertificateError` command. Note: this event does not fire if the certificate error has been allowed internally. Only one client per target should override certificate errors at the same time.

<b>Signature:</b>

```typescript
export interface CertificateErrorEvent 
```
