@Lavan08, it's code templates is an unreleased feature that is available in v3-beta branch.

You can either build from the source or install it with go install -v github.com/projectdiscovery/nuclei/v2/cmd/nuclei@v3-beta

@ehsandeep
I would like to bring to your attention that the issue persists. Additionally, I have noticed that the documentation does not provide a detailed description of this feature, mentioning only the necessity to run the template with the -code switch. Could you please clarify whether this feature is currently unreleased?
Thank you for your assistance.

@MasoudAbdaal this one is released long back and you can see existing code template example here - https://github.com/projectdiscovery/nuclei-templates/tree/main/code/cves

I still have problem to run code templates. Also signed python hello world example template. Is there any additional configuration or specific setup to run it?

See the warning, you need to sign the template before you can use it, it's getting skipped as it's unsiged.

Thank you! It worked for the sample template which exist in https://github.com/projectdiscovery/nuclei/blob/main/integration_tests/protocols/code/py-snippet.yaml
but when I modified it and sign it again, I got the same error
