ZAP seems to incorrectly report path traversal vulnerability in Angular app

I’m running OWASP ZAP as part of an automated CI/CD process. I am doing a spider and active scan. The report showed that there is a Path Traversal vulnerability.

This is an Angular 2 site and the javascript application is downloaded and runs in the local web browser so there wouldn’t be anything revealed on the server.
