Dear team, I would like to combine the current run html results with the previous run file. I tried the options given in the docs as

ExtentSparkReporter spark = new ExtentSparkReporter("spark.html");
JsonFormatter json = new JsonFormatter("extent.json");
ExtentReports extent = new ExtentReports();
extent.createDomainFromJsonArchive("extent.json");
extent.attachReporter(json, spark);

But i am getting the below error- Could you please help me on this.
