Understanding the Playbook Configuration:

The "Malicious File Detect" playbook is designed to create an incident when a malicious file detection event is triggered.

The playbook includes tasks such as Attach_Data_To_Incident, Create Incident, and Get Events.

Analyzing the Playbook Execution:

The exhibit shows that the Create Incident task has failed, and the Attach_Data_To_Incident task has also failed.

The Get Events task succeeded, indicating that it was able to retrieve event data.

Reviewing Raw Logs:

The raw logs indicate an error related to parsing input in the incident_operator.py file.

The error traceback suggests that the task was expecting a specific input format (likely a name or number) but received an incorrect data format.

Identifying the Source of the Failure:

The Create Incident task failure is the root cause since it did not proceed correctly due to incorrect input format.

The Attach_Data_To_Incident task subsequently failed because it depends on the successful creation of an incident.

Conclusion:

The primary reason for the playbook execution failure is that the Create Incident task received an incorrect data format, which was not a name or number as expected.
