Replace any word character (include digits) to nothing (remove)

Trim: function to strip (deletes) the leading and trailing spaces from a string variable.

Gets the content ‘3 characters from the right’ from ‘cropped text to 6 characters’ ‘from the beginning (0)’

Flowcharts offer more flexibility for connecting activities and tend to lay out a workflow in a plain two-dimensional manner. The most important aspect of flowcharts is that, unlike sequences, they present multiple branching logical operators. These enable you to create complex business processes and connect activities in multiple ways.
Flowcharts tend to be used for workflows which contain multiple decision points.

Reads all characters from a specified PDF file and stores it in a string variable by using OCR technology.

Flowcharts come with the Auto Arrange option in the context menu.

There are two activities that are specific to state machines, namely State and Final State, found under Workflow > State Machine.

TrimEND
TrimEnd removes all trailing occurrences

A state machine workflow must have one and only one initial state, and at least one final state.
Each state that is not a final state must have at least one transition.

Account – The account used to access the messages that are to be retrieved.

A PDF file that is originally generated in a computer, aka “born digital“, meaning that it was created from an original electronic version of a document. One quick way to tell that a PDF is native is that you can select blocks of text in the file.

MailFolder – The mail folder from which the messages are to be retrieved.
Account – The account used to access the messages that are to be retrieved.

(0)=Hello
(1)=World
(2)=Its
(3)=Me
Result
Me

Transition contain three sections, Trigger, Condition and Action, that enable you to add a trigger for the next state, or add a condition under which an activity or sequence is to be executed.

System.Net.MailMessage

You can only create one initial state, yet it is possible to have more than one Final State.

DateTime.Today.AddDays(-2) represents previous 2 days

Mention the default using “Date“ double quotes

Replace any non-word character to nothing (remove)

The Anchor Base activity consists of two main blocks: Anchor and Action.
The Action block is where we can configure the activity which is to be executed on the target UI element once the Anchor is identified.

Because Outlook Should be locally installed
so authentication not required

LEFT
Retrieves the text from the variable from LEFT
Gets the content 7 characters from the left

fatal when a key activity might not work, and the process will not be able to complete without it.

Verbose level generates default logs for the execution of each Activity, allowing a much more in-depth diagnosis by giving more information about the values of variables and arguments.
You can generate verbose logs by enabling the ‘Log Activities‘ option in Studio.

User-defined logs are generated according to the process designed by you in Studio, when using Log Message Activity or Write Line Activity.

Unlike the Step Into action, Step Over does not open the current container. When used, the action debugs the next activity, highlighting containers (such as flowcharts, sequences, or Invoke Workflow File activities) without opening them.
This action comes in handy for skipping analysis of large containers which are unlikely to trigger any issues during execution.
Step Over is available using the F10 keyboard shortcut.

It can be set to display the values of variables or arguments, and values of user-defined expressions that are in scope. These values are updated after each activity execution while debugging.

Catches – The activity or set of activities to be performed when an error occurs.
Exception – The exception type to look for. Please note that you can add multiple exceptions.
If more than one excepts fits one that‘s specific match that will be executed

Folder is not created is fatal level

The types of logs generated by the execution of a process are called Robot Execution Logs. They can be further split into default logs and user-defined logs.

The Global Exception Handler has two predefined arguments, that shouldn‘t be removed.
errorInfo has IN direction
result has OUT direction

Trace category in the Output panel would you leave enabled to check the Fatal level logs

Warning
Any important data that you need to stand out from the rest of the log information.

an error is thrown because the wrong credentials were provided by the user.

it can be used for inspecting data available at a certain point during debugging. It can evaluate variables, arguments, or statements. To do so, simply type the variable or argument name in the Immediate window and press Enter.

Retries the contained activities as long as the condition is not met or an error is thrown.
As per the question condition is met
it will execute only one time
“Referesh button was clicked“

It‘s useful to know what the default Robot Execution logs are so we don‘t duplicate data and make the log files larger and harder to read. If you need more information revisit the Default logs section in this lesson.

The Locals panel displays properties or activities and user-defined variables and arguments. The panel shows:
Exceptions – the description and type of the exception.
Arguments
Variables
Properties of previously executed activity – only input and output properties are displayed.
Properties of current activity

The Immediate panel is only visible during debugging, and it can be used for inspecting data available at a certain point during debugging. It can evaluate variables, arguments, or statements. To do so, simply type the variable or argument name in the Immediate window and press Enter.

Step Out
As the name suggests, this action is used for stepping out and pausing the execution at the level of the current container. Step Out completes the execution of activities in the current container, before pausing the debugging. This option works well with nested sequences.
Step Out is available using the Shift + F11 keyboard shortcut.

verbose level provides all the informatiion

Verbose-Level 1
Trace-Level 2
Information-Level 3
Warning-Level 4
Error-Level 5
Fatal-Level 6

ContinueOnError property is set to True
So
Try Catch will  not catch the exception
After trying 2 times
“Completed“ will be printed

As you noticed
ContinueOnError property set to False
so any exception thrown will be caught
After Retrying 2 times
catch block will be executed “Exception“
then “Completed“

During process execution, the Robot generates a message (Log) for each step along the way. These are gathered and stored in a Log File. The overall operation of gathering and storing Logs is called Logging.

Activities which are supported
ElementExists
ImageExists
Check App State
Check True
Check False
Text Exists

Error
An error has occurred. The robot will try to recover and move on with the next item.

The Global Exception Handler is a type of workflow designed to determine the process‘ behavior when encountering an unexpected exception. This is why only one Global Exception Handler can be set per automation project.

NumberofRetries left it blank so by default it will take value as 3
so it will try for 3 times
finally exception thrown

Logs are in the form of JSON, key-value pairs where the field is the key and the information in that field is the value.

Data is missing
without data if you access it
it will throw NullReferenceException

The Global Exception Handler is not available for library projects, only processes.

Using Try/Catch we can solve the issue

Step Into
Use Step Into to debug activities one at a time. When this action is triggered, the debugger opens and highlights the activity before it is executed.
When Step Into is used with Invoke Workflow File activities, the workflow is opened in a new tab in ReadOnly mode and each activity is executed one by one.
The keyboard shortcut for Step Into is F11.

the folder does not exist and next we will try to create it to be able to save the PDF files to it.

Variables or arguments can be added to the Watch panel in the following ways:
In the Watch panel, click the Add Watch field and type the name of the variable or argument;
In the Locals panel, right-click a variable or argument and select Add to Watch;
In the Variables or Arguments panel, right-click a variable or argument and select Add Watch.

The Locals panel displays properties or activities and user-defined variables and arguments. The panel shows:
Exceptions – the description and type of the exception.
Arguments
Variables
Properties of previously executed activity – only input and output properties are displayed.
Properties of current activity

They can be either default logs or user-defined logs.
They are messages generated by the execution of a process

Catches – specifies the exception type and, optionally, holds an activity that informs the user about the found exception;
There is no limit to how many Catches you can use in a Try Catch activity.

ContinueOnError property Enabled True
so it will not throw any exception
NumberofRetries default value is 3
it will print
Try
Try
Try

When using the Global Exception Handler with a project that includes a Try Catch, make sure to group activities into a Sequence inside the Try container. Otherwise, the Global Exception Handler does not execute.

2022-05-18_Execution flle opened if you select Logs

1.Check the logs for the error location and navigate to the activity with the exception
2. Validate the Selecctor and add a breakpoint at the actvity
3. Update the Selector causing the exception to make it more dynamic and robust
4. Run in Debug mode to ensure the process runs without the exception
