Error and warning messages and their meaning

Introduction

This article summarizes all possible error/warning messages that may be returned to the user and why it is sent.

Overview

Status change: highlights whether the case status switches because of this message (if it says running, there is no status change)

Area: highlights to what area the warning/error relates.

Message: body of the warning/error

Type: explains the type of message. Messages of type 'Info' are purely informative, messages of type 'Warning' are sent when a potential error may occur. Finally, error messages are sent when the user must change something about the input.

Input error: highlights whether this warning/error is due to an input error or not
