RTCError: sctpCauseCode property

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.

The read-only sctpCauseCode property in an RTCError object provides the SCTP cause code explaining why the SCTP negotiation failed, if the RTCError represents an SCTP error.

Value

An unsigned long integer value specifying SCTP cause code explaining why the error occurred. This property is null if the error isn't an SCTP error, with its errorDetail property set to sctp-failure.

The standard SCTP error cause codes, numbered 1-13, are defined in the SCTP specification: RFC 4960, section 3.3.10.
