[StackOverflow] Creating a new Visitor leads to wrapping value error

[tanishqkancharla]

Hello! I love this project! For my purposes, I've been making a Visitor that renders markdown text to SwiftUI Views. However, accessing any data of a node leads to the following error:

Fatal error: Couldn't wrap node of type: cmark_node_type(rawValue: 0): file .../BaseNode.swift, line 23

The code breaks on the line I print node.children in rendering a heading node in my visitor class (but the same error occurs on other nodes as well):

func visit(heading node: Heading) -> Result {
        print("Heading node \(node)")
        print("Children are \(node.children)")
        print("Depth is \(node.nestDepth)")
        
        return AnyView(EmptyView())
    }

This is where I initiate the AST traversal:

//       text is equal to "### First block"
        let node = try Down(markdownString: text).toAST().wrap() as! Document
//        let st = node.accept(AttributedStringVisitor(styler: DownStyler()))
//        print(String(reflecting: st))
        return node.accept(Viewer())

The confusing part is, this error only happens occasionally, and if I uncomment the code above that uses the default styler traversal, the code always runs fine, which makes me think it has to do with a problem with the lazy variables I'm using. Does anyone have any insight on this?

Hi there 👋 Please consider asking general questions about working with cmark and Down on StackOverflow.com rather than here. The only issues that should be filed on this GitHub repo is if it's a bug in Down that needs addressing. Thanks!
