Description

For fault tolerant, when something is wrong in Evaluator or Context, we need to throw proper exception to inform the driver with defined exceptions and messages. This Jira is to

• Identify those exceptions
• Identify the places in the code where we should catch the exception and throw
• Implement it in the Evaluator and Context code.
