When Implementing CI/CD with Azure Devops , Error converting value "AppTest" to type 'System.Nullable<UiPath.Orchestrator.Web.ClientV3.RobotType>'

Hi everyone,

I am implementing a CI/CD pipeline for a UiPath Test Automation project using Azure DevOps and Automation Cloud Enterprise Trial.

The pipeline successfully performs the following actions:

  • Packages the Test Automation project
  • Deploys the package to Automation Cloud
  • Creates a temporary Test Set
  • Starts the Test Execution
  • Executes the test successfully
  • Test Execution is marked as Finished in Orchestrator

However, after the test execution completes, the Azure DevOps pipeline fails while retrieving the test execution result.

Environment

  • Automation Cloud: Enterprise Trial
  • UiPath Studio: 2026.0.197 STS
  • Azure DevOps UiPath Integration Extension: 6.1.11078541 (Latest)
  • UiPath CLI:
uipcli 25.10.7+845597a611926f907c660c73cd3a55557ab6c757
  • Azure DevOps Agent: Self-hosted Windows Agent

Pipeline Output

The test starts successfully and then keeps polling:

Running tests...
0 passed, 0 failed or canceled, 1 total.
Waiting for 20s...

Eventually, the task fails with the following exception:

Microsoft.Rest.HttpOperationException: Could not deserialize the response body stream as UiPath.Orchestrator.Web.ClientV3.TestSetExecutionDto.

Error converting value "AppTest" to type
'System.Nullable<UiPath.Orchestrator.Web.ClientV3.RobotType>'

Requested value 'AppTest' was not found.

What I have verified

  • The package is deployed successfully.
  • The Test Execution is created successfully.
  • The robot executes the workflow successfully.
  • The Test Execution status in Orchestrator is Finished.
  • Automation logs show that the execution started and ended successfully.

The failure occurs only when the Azure DevOps task attempts to retrieve the test execution result.

Question

Has anyone encountered this issue before?

Is this a known compatibility issue between:

  • UiPath CLI 25.10.7
  • Azure DevOps UiPath Integration Extension 6.1.11078541
  • Latest Automation Cloud Enterprise Trial

or is there any configuration or workaround that I should consider?

Any help would be greatly appreciated.

Thank you!

It seems that the UiPath CLI Test task from UiPath.CLI.Windows 25.10.7 is not supporting the new API in Test Manager and also is not backwards compatible with the Orchestrator API. It seems that it was fixed in the UiPath.CLI.Windows 25.10.10. Reference: CI/CD integrations - 25.10.10

Try using the UiPath.CLI.Windows 25.10.21 from https://uipath.visualstudio.com/Public.Feeds/_artifacts/feed/UiPath-Official/NuGet/UiPath.CLI.Windows/overview/25.10.21 under the UiPath Install Platform task after you downloaded and placed it in a known location in the agent machine (e.g. $(Agent.ToolsDirectory)\nupkg\UiPath.CLI.Windows.25.10.21.nupkg ).
