https://github.com/simonw/datasette/blob/49d6d2f7b0f6cb02e25022e1c9403811f1fa0a7c/datasette/app.py#L1024-L1029

404 errors are rendered by looking for a template from `[""404.html"", ""500.html""]`.

`404.html` doesn't actually ship with Datasette (plugins or custom template directories can provide it). So the `500.html` template is used.

That template extends `base.html`, which expects there to be `base_url` and `app_css_hash` variables. But as you can see in the excerpt above, those variables are not being passed to the template context when the error page is rendered.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",626171242,
