Field not found (class: ${className}, field: ${fieldName})

Error message

Field not found (class: ${className}, field: ${fieldName})

What it means

ReflectionUtils.setFieldValue walks the class hierarchy via findField and throws ExplicitException when the field cannot be located; the message interpolates the class and field names. This indicates a programming/configuration mismatch, not user input error.

Solutions

1. Check the exact field name and target class (inherited fields must exist up the hierarchy).
2. Use findField and handle a null return when the field is optional.
