Export Import failure while migrating code from One instance to another

Our Dev and Prod versions of Matillion sit on two different EC2 instances. We are trying to migrate the code from one instance to another using Export and Import features of Matillion. While we were able to successfully export the project into JSON file, while importing it in a different environment, the import fails with "Error parsing file" error. Any idea what is causing this error?

Just thought I'd ask you this first- are Dev and Prod running the same version of Matillion? I understand there can be problems with importing a project created in a newer version than the target instance.

Sorry for the delayed response. Yes. Both are on the same version and in two different EC2 instances. And sometimes the code import works.. and sometimes it doesn't.. seems like a bug​

Figured out a way to integrate Code Base to Git repository. This solves our purpose for migration.
