    # The endpoint_id of the current endpoint to be passed as caller_id when

    # calling another service.

    # Get the constant name for a field value

    # @param field_value [String] The field value (e.g., "gl_user_id")

    # @return [String, nil] The constant name (e.g., "GL_USER_ID") or nil if not found
