Incorrect Product Version
A simple version check is added to the Business Connector to avoid that users are trying to use an incompatible version for accessing the Ometa framework. Mixing such incompatible versions may lead to data corruption in the framework repository (database and files).
So, both the BCM and Business Connector must have the same product version (= semver value).
Product Versions Do Not Match

Probably an attempt is made to connect with the Business Connector to a different environment that contains a different version of the framework. Check the URL used to define the environment to connect to, and try again.
Product Version Not Found

This error might mean either trying to connect to an older framework version that doesn't have that version check. In this case, check the URL used to define the environment to connect to, and try again.
Or, it might mean an issue with the BCM process. In this case it might be useful to contact support for assistance.
