Library Compile Error

June 10, 2021, 8:58 am
$

Hello,

I have a custom library that holds several functions prepared in advance for things like handling emails, Slack, or login scripts.

I recently updated the Slack Activities package in order to update my scripts, but I’m getting a compile error that I can’t seem to find anything about:

The assembly compilation returned the following errors:

  • ‘Func<IList, IList>’ does not contain a constructor that takes 0 arguments
  • ‘ScopeActivityBase.TelemetryEnabled’ is obsolete
  • ‘ScopeActivityBase.TelemetryEnabled’ is obsolete
  • ‘Func<IList, IList>’ does not contain a constructor that takes 0 arguments
  • ‘Func<IList, IList>’ does not contain a constructor that takes 0 arguments
  • ‘Func<IList, IList>’ does not contain a constructor that takes 0 arguments
  • ‘ScopeActivityBase.TelemetryEnabled’ is obsolete
  • ‘ScopeActivityBase.TelemetryEnabled’ is obsolete
  • ‘Func<IList, IList>’ does not contain a constructor that takes 0 arguments
  • ‘ScopeActivityBase.TelemetryEnabled’ is obsolete

Does anyone know what this means and how to fix it? Could this be an internal issue with the latest Slack activities package? No longer being able to update our custom library is holding us back on developing new scripts.

Thanks in advance!

Exchange services : Send Email : No mailbox with such guid

Hi All,

I’m trying to connect to shared mailbox using exchange services. I’m able to read emails using “Get Mail messages” however when I tried sending emails using the same exchange server and settings, it is throwing error saying “No mailbox with such guid”.

Exception details:
Source: Send Exchange Mail .

Message: No mailbox with such guid.

Exception Type: Microsoft.Exchange.WebServices.Data.ServiceResponseException

An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is:
Microsoft.Exchange.WebServices.Data.ServiceResponseException: No mailbox with such guid.

  • at UiPath.Mail.Exchange.Activities.ExchangeScope.OnFaulted(NativeActivityFaultContext faultContext, Exception propagatedException, ActivityInstance propagatedFrom)*
  • at System.Activities.Runtime.FaultCallbackWrapper.Invoke(NativeActivityFaultContext faultContext, Exception propagatedException, ActivityInstance propagatedFrom)*
  • at System.Activities.Runtime.FaultCallbackWrapper.FaultWorkItem.Execute(ActivityExecutor executor, BookmarkManager bookmarkManager)*

I have explored couple of blogs with same issue, wherein they’re asking to check if mailbox account is licensed or not - which is, in reality, a licensed one.

Could you please help, if anyone has encountered/tackled such kind of issue?

Appreciate your help!
Thanks in advance,
Rohan

Exception.source not retrieved correctly

November 20, 2018, 1:09 am
$

Hello everyone!

I’m facing an issue here after upgrading one of our robots to the latest version of UiPath Studio.

All of our projects are FlowCharts invoked through a state machine with a Try/Catch, which allowed us to get the Exception.message and Exception.source accurately and easily.

Unfortunately, since the update, the Exception.source is not getting retrieved correctly anymore. We need this information to be able to debug our projects effectively.

Now, the only info we get from the Exception.source is either System.Activities or UiPath.UiAutomation.Activities but not the name of the activity itself.

Do you know how to get around this issue?

Thanks a lot in advance!
