Resolving The Problem

If an environment variable is created and initialized explicitly in the custom code, care should be taken to make sure that all the necessary attributes in the variable are populated. If not, a NullPointerException might be encountered.

Ideally the environment variable set by the MCF infrastructure should be used.

For the particular issue, using the out of box User Exit with the infrastructure provided environment variable instead of custom API, resolved the issue.
