There is a process that has failed to execute. It is listed as ‘Faulted’.
And yet there is no log entries.
In the Job Details tab:
* Raw message: Cannot create unknown type '{http://schemas.uipath.com/workflow/activities}LogMessage'. System.Xaml.XamlObjectWriterException: Cannot create unknown type '{http://schemas.uipath.com/workflow/activities}LogMessage'. at System.Xaml.XamlObjectWriter.WriteStartObject(XamlType xamlType) at System.Xaml.XamlWriter.WriteNode(XamlReader reader) at System.Xaml.XamlServices.Transform(XamlReader xamlReader, XamlWriter xamlWriter, Boolean closeWriter) at System.Activities.XamlIntegration.FuncFactory1.Evaluate() at System.Activities.DynamicActivity.OnInternalCacheMetadata(Boolean createEmptyBindings) at System.Activities.Activity.InternalCacheMetadata(Boolean createEmptyBindings, IList1& validationErrors) at System.Activities.ActivityUtilities.ProcessActivity(ChildActivity childActivity, ChildActivity& nextActivity, Stack1& activitiesRemaining, ActivityCallStack parentChain, IList1& validationErrors, ProcessActivityTreeOptions options, ProcessActivityCallback callback) at System.Activities.ActivityUtilities.ProcessActivityTreeCore(ChildActivity currentActivity, ActivityCallStack parentChain, ProcessActivityTreeOptions options, ProcessActivityCallback callback, IList1& validationErrors) at System.Activities.ActivityUtilities.CacheRootMetadata(Activity activity, LocationReferenceEnvironment hostEnvironment, ProcessActivityTreeOptions options, ProcessActivityCallback callback, IList1& validationErrors) at System.Activities.Hosting.WorkflowInstance.ValidateWorkflow(WorkflowInstanceExtensionManager extensionManager) at System.Activities.Hosting.WorkflowInstance.RegisterExtensionManager(WorkflowInstanceExtensionManager extensionManager) at System.Activities.WorkflowApplication.EnsureInitialized() at System.Activities.WorkflowApplication.Enqueue(InstanceOperation operation, Boolean push) at System.Activities.WorkflowApplication.SimpleOperationAsyncResult.Run(TimeSpan timeout) at System.Activities.WorkflowApplication.BeginRun(AsyncCallback callback, Object state) at UiPath.Executor.RobotRunner.<RunWorkflow>d__126.MoveNext()
I am afraid I have no other details to provide.
There are no entries found in the logs even after filtering them by the various log levels.
Kindly assist.
Thanks a lot.

@RobinsonFrancis,

Try this approach.

  1. Take a backup of your project’s project.json file
  2. Delete the project.json file from project folder
  3. Close the project from studio if open
  4. Open the project by double clicking on the Main.xaml file
  5. Let the studio rebuild the project.json with required packages and versions.
  6. Check if the error resolved now
