Can you please try again using the dev branch to see if you encounter the same error?

[sttrv]

Oh yup, still does. You can try it yourself as described above, use workflows that includes headless templates (you can use any of the community maintained nuclei templates). Then run it without -w and without -headless

Can you please share the complete cmd?
