Maximum call stack size exceeded

[lxnagel]

Running in a bookworm-tls node container, and this is what I got after adding "all the folders" I want to check. Installed the npm package from npmjs.
Output

Performing Check

    Error:
     - Maximum call stack size exceeded

And this is the folder/file struct I have drafted and does exist. Somehow the last folder here has a larger set of files and sub-folders. Any recommendation?

@lxnagel can you provide the folders/files structure you are checking against? or the minimum folder setup where you can reproduce this bug?

[lxnagel]

Working on it without providing the real data.
While doing this I found something where I'm not sure if bug or feature:

{
            "type": "directory",
            "name": "TestReports",
            "rules": [
                {
                    "type": "directory",
                    "name": "NUnit",
                    "rules": []
                },
                {
                    "type": "directory",
                    "name": "StaticCode",
                    "rules": []
                },
                {
                    "type": "directory",
                    "name": "UnitTests",
                    "rules": []
                }
            ]
        }

empty_folder.zip
this leads to no successfukl validation if the test.log file in TestReports/NUnit is created. Is an emtpy folder tree not allowed? Somehow at least one file seems to be needed.

[lxnagel]

In my real-world thing, there are 600 files in deeper folders (TestReports is 3 layers deep), yet it also crashes with dummy files:
max_stack_folder.zip

Parallel I would now to try debugging it as well.

[lxnagel]

While debugging I found something: the code does build the ascii-tree regardless required or not. Yet in the helper file module, the string is not being built successfully.
I was able to get the rules to be verified when I limit the file-list to e.g. size 1. Then the script was executing. Proceeding to find a solution about building the ascii-string.

edit: I did not yet "fix" the helper function to be not recursive as I noticed in my example there are 13k files
