@lohrm-stabl could you tell me any repository that I can check?

[lohrm-stabl]

I don't have any public repository where this happens. We also stopped using the trivy action (since it didn't work).

[nayuta]

@lohrm-stabl OK. Are these TypeScript projects, right?

[lohrm-stabl]

Exactly. https://developer.hashicorp.com/terraform/cdktf to be specific

[nayuta]

@lohrm-stabl I found the problem that trivy_command and trivy_target are necessary but not supplied in your config. However, we must warn when these parameters are not provided, so I created the PR.
