How to log inside "Invoke code" activity?

Help
1

Hi,

I’m wondering whether it is possible to log messages inside “Invoke code” activity in the same manner as the “Log message” activity does? Is there for example a particular namespace that contains the logging methods so that I could use them inside “Invoke code” activity? This would be useful so that I could get more fine-tuned information about what happens inside the “Invoke code” activity.

You could try to use Console.WriteLine ?
It should basically log Trace level messages. This is by far the easiest way of doing it that I can think of.

uipath.Core.Activities.LogMessage()

Thank you for your reply. I have been using Console.WriteLine method so far but the problem with this is that log messages don’t appear in Orchestrator even though I specify the log level as Trace.

Thank you! This seems to do the trick. Using this approach I managed to get the logging working with the following piece of code:

Dim logMessage As UiPath.Core.Activities.LogMessage = New UiPath.Core.Activities.LogMessage()
logMessage.Level = UiPath.Core.Activities.CurentLogLevel.Error
logMessage.Message = "Hello World!"
Dim logInvoker As WorkflowInvoker = New WorkflowInvoker(logMessage)
logInvoker.Invoke()

Hi forum team.

I was trying to find how to log messages from invoke codes and I came across this thread.
Unfortunately, I believe this no longer works on newer versions of UiPath. Could you provide the current solution or reopen the following thread?

Best regards,
Pedro.

You can always use message boxes for debugging. Just type before/after line you want to check:

UiPath.NativeMessageBox.ShowInfo(“Your message” + youCanUseVariables.toString)

Hi Ledorin,

I was trying to call this activity as per you suggested, though I got the Object Null exception.
I have attached the workflow and the screenshot I am getting while executing the workflow.
Need your help.

As mentioned above Console.WriteLine was working

Overcoming the issue with the InArgument /Conversion we can do:

Code:

Dim wl As System.Activities.Statements.WriteLine = New System.Activities.Statements.WriteLine()
wl.Text = New InArgument(Of String)("Hello From WriteLine")
Dim res As IDictionary(Of String, Object) = WorkflowInvoker.Invoke(wl)

Unfortunatly the same was not working on the first hit with logMessage. But the LogMessage Activity was created with the Input Arguments for LogLevel and Message in the same way and looked ok for this part
