Hi @ytella,

Thanks for the response.

I did follow the mentioned steps but it didn't worked out.

The project was build on ThingWorx Studio 1.5.0. I did a fresh install on new machine and imported the project folder of ThingWorx 1.5.0 to ThingWorx Studio 8.2.2 where it was incremental upgrade on project files as i could see in the logs. But it failed on the final project build with mentioned error.
