Hello,
I am currently working on the client hash project within the UiPath academy. I have referenced the walkthrough pdf for some hints on how to work through some areas. When running the process I am seeing the error: “System1NavigateTo_WIDetails - Invoke Workflow File (System1\System1NavigateTo_WIDetails.xaml): Object reference not set to an instance of an object”
I am a bit confused on what is failing to be referenced here since it looks like it’s unable to find the XAML despite it being referenced in the output. Is this indicative of the file not being found or an argument within the XAML file? Thank for any advice you can provide.
Hi @StefanGrish
Could you check the arguments of the Invoke Workflow File? you might have assigned an Argument to a variable, that does not exist or is out of scope.
in_WIID & in_System_WorkItemURL are declared on the workflow. work item url is defined in the config file. in_WIID is not declared on the workflow file but it’s on the process.xaml with in_TransactionItem(“WIID”).ToString as the value on the invoke workflow activity.
Are both of these values sent into the System1NavigateTo_WIDetails.xaml when it is invoked? Also, try to Debug with “Execution Trail” to exactly know where the failure is happening: i.e: Is it happening when the workflow is invoked or within the workflow when an activity is being executed.
Could you open the arguments panel of the Invoke Workflow file and share the screenshot.
Also show your data manager panel. Let’s debug what the issue is.
You are using RE by the looks of it. I want to know how are you passing these values.
