Handle exceptions from JSON utility APIs

This commit adds proper handling for exceptions thrown by JSON utility
APIs. In some cases, input parameters were being accessed directly from
the JSON object without verifying their presence, leading to potential
exceptions. This commit ensures safer access to JSON fields to prevent
such errors.
