While I am trying to view the output of a analyzing, I found when I click on the file to view source code and the analyzing result, the page failed to load and the following error message appears on console session:

I'm currently using Python 3.13.0 on WSL 2.

I think this could be a problem with APIs used by pygments having changed. I think the line in question (in the current version) is: https://github.com/pygments/pygments/blob/27649ebbf5a2519725036b48ec99ef7745f100af/pygments/formatters/html.py#L979C27-L979C31

Can you try a more modern version of pygments?

[ivanperez-keera]

The signature of wrap in the view's Formatter (which inherits from HtmlFormatter) is compatible with pygments':

IKOS:

class Formatter(HtmlFormatter):                                                  
    def wrap(self, source):

Pygments:

class HtmlFormatter(Formatter):
    def wrap(self, source):

[ChAoSUnItY]

Yes, I tried the latest pygments and it's fine. I was installing IKOS from homebrew just today, is it caused by improper version locking?

[ivanperez-keera]

Sounds like it.
