Error handling

Because bots are typically used on an unattended computer, no one is available to click OK to continue processing when an error occurs. Use the Begin/End Error Handling statements to gracefully handle error dialogs.

When added to a task, the Error Handling allows us to gracefully handle any errors that occur.

Handle errors as follows:

• Take Snapshot: It saves a snapshot of the screen at the moment of the error. A screenshot is sometimes the best way to determine the cause of an error when running on an unattended Bot Runner.
• Run Task: Starts a new Task when an error occurs. This Task can do functions, for example, cleaning up temporary files.
• Log Data into File: Writes a new log entry into the specified log file. This log entry can also contain a time stamp, which is useful for determining exactly when the error occurred. Using the system variables for $Error Line Number$ and $Error Description$ provides useful data for the log.
• Send Email: Sends an emailed error report which can contain a screenshot of the error (see Take Snapshot) and variable values to help troubleshoot the issue.
• Variable Assignment: Sets a value to a specific variable. This is useful for tracking whether an error occurred in the task, then doing other events, for example, logging task successes and failures.
• Set Task Status: Reports a Fail or Pass condition to the Control Room on an error. The Pass condition is useful when an error condition is expected but you want to ignore it and continue.
