The above error is valid and the reason for the above error is below.
1: In the application which is exported user have some "Shared Components" alias SC assigned to certain server types
2: Using the SC flows users had created some processes in specific environments and published the same.
3: Later on in progressive design phase they did some refactoring and unassigned SC's from all server types and map them to specific dedicated server types. Doing so have break the process which can be found when you try to go to process tab and check for conflicts in that process.
4: But as the published process is still holding context of actions and flows from last associated SC the exported JSON has those attributes and hence importing same fails with above error.
