The CrashReportBody interface of the Reporting API represents the body of a crash report (the return value of its Report.body property).
A crash report is generated when a document becomes unusable due to the browser (or one of its processes) crashing. For security reasons, no details of the crash are communicated in the body except for a general crash reason.
Properties
reason
A string representing the reason for the crash. Current possible reasons are:
oom: The browser ran out of memory.
unresponsive: The page was killed due to being unresponsive.
Examples
Crash reports are generally only retrievable via endpoints set up using the Report-To header. It is difficult to retrieve a crash report via a ReportingObserver, as by that point the page would have crashed!
Some sample JSON might look like this:
{"type":"crash","age":42,"url":"https://example.com/","user_agent":"Mozilla/5.0 (X11; Linux x86_64; rv:60.0) Gecko/20100101 Firefox/60.0","body":{"reason":"oom"}}
Note: Crash reports are always delivered to the endpoint group named default; there is currently no way to override this. If you want to receive other kinds of reports, but not crash reports, make sure to use a different name for the endpoint group that you choose for those reports.
