The sourceFile read-only property of the InterventionReportBody interface returns the path to the source file where the intervention occurred.

A string, or null if the path is not known.

In this example we create a new ReportingObserver to observe intervention reports, then print the value of sourceFile 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.sourceFile);
}, options);
