What OS are you using (uname -a, or Windows version)?

Darwin 21.1.0 Darwin Kernel Version 21.1.0: Wed Oct 13 17:33:23 PDT 2021; root:xnu-8019.41.5~1/RELEASE_X86_64 x86_64

What programming language are you using (C/C++/Go/Rust)?

go version go1.19.5 darwin/amd64

What did you expect to see and what you saw instead?

Errors should be logged to the console with full information; instead I just get "script error". This works correctly when I run a webserver on 127.0.0.1:8080 and use Navigate("http://localhost:8080"), suggesting the issue is that SetHtml is not actually setting the location correctly.

I suspect this is the offending code (specifically, the nullptr passed as the final argument, which should probably be something like http://localhost/):

  void set_html(const std::string &html) {
    webkit_web_view_load_html(WEBKIT_WEB_VIEW(m_webview), html.c_str(),
                              nullptr);
  }
