# RecoveryError

> Error thrown when a recovery attempt fails.

Raised when the SDK's automatic call-recovery flow fails — for example, after a transient signaling disconnect that exceeds [`maxRecoveryAttempts`](/docs/browser-sdk/v4/reference/client-preferences/max-recovery-attempts). The `action` and `attempt` properties identify which recovery step gave up. When this fires the call has transitioned to `failed`; clean up UI and notify the user.

## **Extends**

* `Error`

## **Constructors**

### Constructor

```ts
