getting error "Object reference not set to an instance of an object

Everything was working fine and all previous snapshots were working fine for sql compare but after the deployment of one object we are getting the error mentioned above. ALso same object is creating a build error in the redgate DLM tool too where the errors reads out as below: The annying part is that when the code was added to the repository, it did not threw an error and we created a script to deploy the code but now after it has been deployed it is causing the error in build and also in sql manual compare where it is not registering as source as in pic below: If I delete the object then it builds but I cannot delete in the database now as it is aleady there to create a new snapshot.
