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 sctpCauseCode read-only property of the RTCError interface 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.
