RTCErrorEvent

Baseline 2026

Newly available

Since April 2026, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

Note: This feature is available in Dedicated Web Workers.

The RTCErrorEvent interface of the WebRTC API represents an error event sent to a WebRTC object. It inherits from the standard Event interface, adding RTC-specific information describing the error.

The error events fired at RTCDataChannel and RTCDtlsTransport are instances of this object.

Note: WebRTC defines other error event interfaces, such as RTCPeerConnectionIceErrorEvent, which are used for errors that have other special information sharing requirements.

Instance properties

Also inherits properties from its parent interface, Event.

error Read only: An RTCError object specifying RTC-specific information about the error. This includes information such as the error type and cause, and the location that triggered the error.
