Hyperledger Fabric Node SDK 1.4 is incompatible with Hyperledger Fabric v2

The Hyperledger Fabric ecosystem has witnessed significant advancements with the release of Hyperledger Fabric v2. However, with these advancements come compatibility challenges, particularly for users of the Hyperledger Fabric Node SDK 1.4. It's crucial for developers to be aware of these compatibility issues to ensure smooth transitions and effective utilization of the latest features.

One of the key compatibility issues arises from the fact that the Hyperledger Fabric Node SDK 1.4 does not support Hyperledger Fabric v2. This lack of support poses limitations on certain functionalities, notably affecting chaincode methods such as sendInstantiateProposal.

The root cause of these compatibility issues lies in the fundamental alterations introduced in the chaincode lifecycle management between Hyperledger Fabric v1.4 and v2. It's essential for developers to grasp these changes to navigate the compatibility challenges effectively.
