    Is Preview Broken in v14?

    On both my v14 sites, when I click 'Save and Preview' I get sent to a page URL that ends with "&culture=invariant"

    This results in an error:

    CultureNotFoundException: Culture is not supported. (Parameter 'name') invariant is an invalid culture identifier.

    System.Globalization.CultureInfo.GetCultureInfo(string name)
Umbraco.Cms.Web.Common.Localization.DynamicRequestCultureProviderBase.<DetermineProviderCultureResult>b__4_0(StringSegment culture)
Umbraco.Cms.Web.Common.Localization.DynamicRequestCultureProviderBase.TryAddLocked(IEnumerable<CultureInfo> supportedCultures, IEnumerable<StringSegment> cultures, object locker, Action<StringSegment> addAction)
Umbraco.Cms.Web.Common.Localization.DynamicRequestCultureProviderBase.DetermineProviderCultureResult(HttpContext httpContext)
Microsoft.AspNetCore.Localization.RequestLocalizationMiddleware.Invoke(HttpContext context)

    If I hand-edit the url to include a culture instead of the word 'invariant' then the page opens fine.

    I saw a couple other users here getting this error but their recent comments were buried at the bottom of an old post: https://our.umbraco.com/packages/backoffice-extensions/plumber-workflow-for-umbraco/plumber-workflow-for-umbraco-discussion-and-troubleshooting/108500-error-on-preview-culture-is-not-supported

    Is this a setting, appsetting, machine setting that I have wrong somehow? It is happening on a new single-language umbraco v14 install so it seems out of the box this way.

    To clarify, I'm running 14.0.2

    Worked around this by adding intercepting and leap-frogging the 'Preview' iframe functionality based on an article https://adolfi.dev/blog/umbraco-preview/

    public class PreviewController : Controller
{
    [HttpGet]
    [Route("umbraco/preview")]
    public IActionResult Index(string id)
    {
        var requestUrl = new Uri(Request.GetDisplayUrl());
        var leftPart = requestUrl.GetLeftPart(UriPartial.Authority);
        return new RedirectResult($"{leftPart}/{id}");
    }
}

    and in appsettings.json Umbraco Globals

    "ReservedPaths": "~/umbraco/preview"

    This also resolved some CORS errors the iframe was introducing, and strips off the &culture=invariant querystring that was causing the error. The drawback is you don't get the different device sizes footer menu.
