Technical Tip: Issue with Automation-Stitch causing autod process crash

Description

This article describes an issue with the automation-stitch feature that causes the autod process to crash after updating to FortiOS version 7.6.7.

Scope

FortiGate v7.6.7.

Solution

When an automation-stitch is configured with the action type 'email', it is possible to customize the email subject and body using predefined parameters available in the current log that triggers the automation-stitch. However, using the parameter %%action%% causes the autod process to crash, resulting in the email not being sent after automation-stitch being triggered.

1. Locate the automation action type email that includes the %%action%% parameter in the subject or body of the automation-action (FortiGate GUI -> Security Fabric -> Automation -> Action -> Email).

2. Remove the %%action%% parameter from the automation-action to prevent the crash.

3. Alternatively, replace %%action%% with %%log.action%% to resolve the issue.

4. Ensure that the automation stitch is functioning as expected after making the changes.
