When i upgraded my Thingworx project from version 1.5.0 to 8.2.2.
Can anyone help me with the possible cause for the error. And how to fix it?
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.
