4. Usage

Here, we've previously demonstrated how to use the "Throw" activity to throw an exception if the "

Welcome to akaBot Support!" element on the akaBot support portal site cannot be found. Now, we'll extend this example by introducing the use of a Catches block to catch this exception and re-throw it.

Note: We’ll be using the workflow created with the "Throw" activity. For more details, please refer to the knowledge base entry on "Throw".

First, open the Catches block and delete the existing Write Line activity.

Next, drag and drop the System > Error Handling > Rethrow activity into the Catches block.

Then, drag and drop a System > Originals > Write Line activity into the Finally block.

In the Text property under Miscellaneous, specify a string or String type variable (e.g., "Run workflow").
Refer to the "Creating Variables" guide for details on variable creation.

Close the support portal and execute the workflow by clicking Home > Start or pressing F5.

When the element "Welcome to akaBot Support!" is not found, a "Runtime execution error" dialog box will appear. Click "OK."

Open the output panel and verify the displayed contents. Since the exception is rethrown in the Catches block, the Finally block is not executed, and "Run workflow" is not displayed.
