Looking at the output it seems that we might use an older version of the DSL logic, because the methods were renamed to follow a uniform snake cased convention.

e.g. toupper -> to_upper and so on.

[parrasajad]

we are using github.com/projectdiscovery/dsl, which might have differences to nuclei DSL functions. Pushed the update to make it uniform across the projects.
