Installed kedro-viz on my env and without --lite it's work as expected. Problem seems to --lite flag only

Hi @lordsoffallen ,

Thank you for raising the issue. Is it possible for you to give us a reproducible code snippet on which we can test and fix the issue. I am curious to know what were your import statements and dependencies (especially the file which has utf-8 dependency or related)

@ravi-kumar-pilla Thanks, I would love to help but I have no idea where the problem is. This is a kedro project with many files inside. Is there like debug option that would output where the utf-8 errors are coming from? I don't know any file that i have that has something to do with utf-8. There are quite python in the project.

I see, Thanks for the response @lordsoffallen . As of now we do not have a debug option to give you a better debugging experience. Based on the error stack trace I think the error is being thrown when we are trying to open a file in the project. We have the below code at kedro_viz/integrations/kedro/lite_parser.py -

       with open(file_path, "r", encoding="utf-8") as file:
            file_content = file.read()

We can improve the error message to know exactly which file is causing the issue, but in the mean time if you would like to contribute, you can debug this file kedro_viz/integrations/kedro/lite_parser.py at parse function. Most probably the error is coming from here which tries to decode a file using UTF-8 encoding. If the file in your project has a different encoding, this will error out. Thank you

I can debug but I still don't see how i can invoke this in my IDE. What I normally do is:

def test_preprocess(self, kedro_session):
    kedro_session.run(node_names=['preprocess'])

Which will just run a node, not idea how to invoke viz programatically so i can step into those lines. Would it be possible to add debug line logs (as it would help debug further issues in the future directly) and then I can upgrade and just enable debug logs? This is not urgent for me btw as without --lite flag, it works for me.
