Invalid xml

Activation failed with Error
Error description : server returned invalid xml

Hey @khaled

Try opening Studio with Administrator permissions and also check if you are behind a firewall.


Try to activate outside the firewall. firewall is blocking the activation

Hey, @Palaniyappan @Lahiru.Fernando @lakshman

I too got an Write range Error with a message :

" is an invalid xml:space value

Any idea on why this error occurs ?

Can you show me the configuration of write range?

Kindly share the property panel screenshot of write range activity
Cheers @NiranjanKN

Hey guys, this is the Write range property panel.

we need mention the cell range atleast β€œβ€ and also the sheet name is to be validated
as we have used filename without exttension as a sheetname, kindly ensure once that file has that sheetname

Cheers @NiranjanKN

Hello, @Palaniyappan
Checked the sheetnames, and it works fine for other files except excel file.

And mentioned the cell range as β€œβ€, still got the same error and this is the error detail.

An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is:
System.ArgumentException: β€˜β€™ is an invalid xml:space value.
at UiPath.Excel.Activities.WorkbookActivity`1.EndExecute(AsyncCodeActivityContext context, IAsyncResult result)
at System.Activities.AsyncCodeActivity.System.Activities.IAsyncCodeActivity.FinishExecution(AsyncCodeActivityContext context, IAsyncResult result)
at System.Activities.AsyncCodeActivity.CompleteAsyncCodeActivityData.CompleteAsyncCodeActivityWorkItem.Execute(ActivityExecutor executor, BookmarkManager bookmarkManager)


This is what something that stucks me
Is there any argument in project.json file has vAlue with space in between
Cheers @NiranjanKN

Hey, @Palaniyappan
I was using workbook activities and so I got this error.
Now, I replaced all workbook activities in Excel and used the Excel Application Scope.
So, the error is solved.
