How to solve InvokeElement error while running project.

Issue Description: The error is triggered on Studio 23.4.4 (migrated project from legacy or created a new Windows project) but not on Studio 23.10.

Using Analyze Project does not show the error. Only on Run the project, Run File, or Debug File I am getting invokeElement error.

Note: In Studio version 23.10, a more descriptive error message will be received:

"Source: Invoke Workflow File
Message: The .xaml workflow cannot be found. Make sure that it is part of the project.
Exception type: System.InvalidOperationException".

Cause:

The error is known as UiPathLocalizedException and it happens when UiPath Studio encounters an error while obtaining the dependency tree for your workflow. Possible causes include an incorrect or missing file path, a corrupted or absent package dependency, or an attempt to invoke a non-existent workflow.


Resolution:

Here are some troubleshooting steps to try:

  1. Check File Path: Ensure the correct file path for the Workflow you intend to invoke.
  2. Check Dependencies: Go to "Manage Packages" and confirm the installation of all necessary dependencies, ensuring they are up-to-date.
  3. Validate Workflow: Make sure the workflow being invoked exists and is not corrupted.
  4. If the problem persists, try to recreate the workflow and see if it helps.


Since the error message refers to an InvokeElement, the first suggestion is to check the Invoke methods used in the project and recreate them if they get corrupted.


In this case, the error was triggered by an empty Invoke Workflow.

To solve the issue, it is necessary to remove or modify the empty Invoke Workflow activity with

""


as the WorkflowFileName and then retry the Run, Run File, or Debug the File (xaml).



If these steps prove ineffective, consider reaching out to UiPath support for further assistance.


After reaching UiPath Support, provide these details in the case:

  • Studio project archived in a zip file
  • The UiPath Diagnostic Tool logs for Studio/Robot/Activities Issue
  • Studio version
  • Project compatibility (Windows Legacy/Windows or Cross Platform)
