The message read-only property of the InterventionReportBody interface returns a human-readable description of the intervention, including information such as how the intervention could be avoided. This typically matches the message a browser will display in its DevTools console when an intervention is imposed, if one is available.
A string.
In this example we create a new ReportingObserver to observe intervention reports, then print the value of message to the console.
const options = {
types: ["intervention"],
buffered: true,
};
const observer = new ReportingObserver((reports, observer) => {
const firstReport = reports[0];
console.log(firstReport.type); // intervention
console.log(firstReport.body.message);
}, options);
