Code modules must be able to load

Solved!
Go to solution

I am calling a VI from TestStand 2019. Analyzing the test step produced no errors and the step executed.

 

I have been adding features to the VI. Now TestStand complains during analysis (not when selecting the VI from within the test step). The JKI JSON library has been part of the VI from day one, but now TestStand complains that the JSON serialization files are bad. I have performed a mass compile with no errors reported. The VI is part of a LabVIEW project. The project shows no missing dependencies. The VI runs from LabVIEW just fine. But TestStand says, "Code modules must be able to load."

 

Thanks for any suggestions or troubleshooting recommendations.

 

Here is what is in the TestStand log file:

 

Header: { VI Path : C:\NASA-AFTU\NAFTU_IVV_LV2020\NAFTU Dashboard.vi }


VI error :

The VI is broken. Please refer to the log file from TestStand for more information

Perhaps this information will be helpful.

 

I originally called the VI from a folder. I moved the LabVIEW project to a new folder on the computer. When I reference the VI from the new folder, Analyze fails. When I reference the VI from the original folder, Analyze succeeds.

I performed a mass compile of the folder, 'C:\Program Files (x86)\National Instruments\LabVIEW 2020\vi.lib\addons\_JKI.lib', which contains the offending JKI JSON libraries, and received this error log:

I am not sure how to resolve this. Can anyone help?

I did not make any changes to the LabVIEW VIs or to the TestStand test sequences. I restarted TestStand and the test sequence analyzed without any errors.
