Error while receiving a byte array from robotic automation
I'm trying to take a screenshot of the web search list (ex: 'keyboard' search on Amazon), convert the png file to byte array, and send the byte array over to pega application.
The following is the C# script I have for doing so:
if (string.IsNullOrEmpty(outputImagePath))
{
return null;
}
OpenSpan.Diagnostics.Diagnostic.TraceVerbose("Script", string.Format("Attempting to grab screen shot {0}/{1}/{2}/{3}", width, height, xCoordinate, yCoordinate));
try
{
Bitmap screenshot = new Bitmap(width, height, System.Drawing.Imaging.PixelFormat.Format32bppArgb);
Graphics screenGraph = Graphics.FromImage(screenshot);
screenGraph.CopyFromScreen(xCoordinate, yCoordinate, 0, 0, new Size(width, height), CopyPixelOperation.SourceCopy);
screenshot.Save(outputImagePath, System.Drawing.Imaging.ImageFormat.Png);
ImageConverter converter = new ImageConverter();
return (byte[])converter.ConvertTo(screenshot, typeof(byte[]));
}
catch (Exception ex)
{
OpenSpan.Diagnostics.Diagnostic.PublishException(ex, null);
return null;
}
I'm trying to send the byte array to a Java Object property in Pega (ByteArray), but when I run the case to see if it got transferred, I get the attached error.

Any suggestions on how to fix this issue, or on the C# code is appreciated. Thanks.

You might want to connect that execution block from your script to the activity. I would suggest providing some verbose, timestamped runtime logs so the failure can be isolated.

What do you mean by "connecting execution block from script to activity"?
and where can I locate the runtime logs so I can provide it here? I'm currently using Pega personal edition.

I connected the execution block from script to activity but I still get the same error in Pega application..
In %appdata%\OpenSpan, which one of these files is the log that I can attach to this post for reference?
Also, since the error occurs in Pega, would you want the Pega log file as well? If so, I went to work\Catalina\localhost\prweb, but which one of these files is the right Pega log file I can attach to this post for reference?

How are you passing the ByteArray to the Pega Application? Currently Runtime is limited to passing scalar data between Pega 7 and an automation, noted here - https://docs-previous.pega.com/pega-rpa/integration-robotic-desktop-automation-pega-platform. I do not think this will be possible.
