A TestStand Step in the distribution uses a LabVIEW property node call configured to be called in the context of a project, but the project is not included in the distribution.
TestStand steps which call LabVIEW modules, including standard VI calls and property node calls, can specify a LabVIEW project. If specified, TestStand uses the application instance of the LabVIEW project when calling the code module. This message indicates that the referenced project is not included in the distribution, which will cause the sequence to fail to execute on the target computer.
Inspect the step in the message details, and add the referenced project to a package in the distribution.
