Hi @arsharthpugazhendhi ,

Thanks for reporting this. Can you try the below command and let me know if "-d" is the problem?

trivy scan2html image tag --scan2html-flags --output interactive_report.html

Also, on which OS are you running this?

Hi @fatihtokus,

The issue occurred because the temporary JSON report file (/tmp/scan2html-temp-report.json) was not found, which caused the HTML report generation to fail. This happens if the Trivy command to generate the JSON report did not execute correctly or if the file was not created in the /tmp directory.

It is Linux environment.
