Don't make people guess to help you.

What Thingworx version, what kind of project (TWX? Java extension?), what kind of migration, from where to where, stack traces etc, it's all unclear.

We are currently using Thingworx version 9.5.0-b143 for all the source and destination systems.

We are trying to migrate a thingworx project. Initialy we used GIT for migrating which worked for the first time. But then it stopped and now the import/export function is not working.

We see the same error when trying migration with Git or Exporting project from source and importing it in the destination.
