MergeReport - Exception at CreateDomainFromJsonArchive

[saravanakumar-nc]

Hi,

I have multiple json file that needs to be merged to generate one final html report file.

Lets say I have 15 files. Some of the files are being merged but some getting these errors.
This is my code to merge the report. I even have the retry mechanism with delay, still I am getting the error.

// Initialize ExtentReports
var extent = new ExtentReports();

// Find all JSON files in the test results directory
var jsonFiles = Directory.GetFiles(testResultsDir, "*.json", SearchOption.AllDirectories);

if (jsonFiles.Length == 0)
{
    Console.WriteLine("No JSON report files found in the specified directory.");
    return;
}

Console.WriteLine("JSON files :- "+ Environment.NewLine + String.Join(Environment.NewLine, jsonFiles));

int i = 0;
foreach (var jsonFile in jsonFiles)
{
    int retry = 0;
    bool isFileAttached = false;
    Console.WriteLine("Attaching File-" + ++i + ": " + jsonFile);
    while (!isFileAttached && retry < 5)
    {
        try
        {
            extent.CreateDomainFromJsonArchive(jsonFile);
            isFileAttached = true;
            break;
        }
        catch (Exception e)
        {
            Console.WriteLine("Exception while Attaching File-" + i + ": " + jsonFile);
            Console.WriteLine(e.Message + ": " + e.StackTrace);
            Thread.Sleep(1000);
            Console.WriteLine("Re-try attempt [" + ++retry + "] to attach the File-" + i + ": " + jsonFile);
        }
    }
}

var mergeSparkReporter = new ExtentSparkReporter(testResultsDir + @"\Final\merged-extent-report.html");
mergeSparkReporter.LoadJSONConfig(Utils.PROJECT_ROOT_PATH + @"\spark-config.json");
extent.AttachReporter(mergeSparkReporter);

// Generate the merged HTML report
extent.Flush();

This the stacktrace of the exception.

Any help would be appreciated.

Thanks,

I believe the issue is with Extenttest.Fail(Exception). If i use Extenttest.Fail(Message) everything looks good.
