500 error on Custom Error Pages

[jamierytlewski]

I've created custom error pages and they use the same layout/template as all my other pages. I use @Html.MvcSiteMap().SiteMapPath() to get sitemap path on each page.

Recently (not sure which version), but now I'm getting the error:

Invalid URI: The format of the URI could not be determined.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.UriFormatException: Invalid URI: The format of the URI could not be determined.

Version 4.6.1 added full support for absolute URLs, so the URL parsing was changed quite a bit for explicit URLs. The most likely cause is that you are setting the Url property explicitly to a format that is not supported.

The only formats that are officially supported are:

Format	Example
Absolute URL	http[s]://www.somewhere.com/some-page?a=b
Root Relative URL	/some-page?a=b
Virtual Application Relative URL	~/some-page?a=b

This applies to the Url, CanonicalUrl, and ImageUrl properties/XML attributes.

This is what it looks like:

<httpErrors errorMode="Custom" defaultResponseMode="ExecuteURL" existingResponse="Replace">
      <remove statusCode="404" subStatusCode="-1" />
      <remove statusCode="500" subStatusCode="-1" />
      <!-- full url when responsemode is Redirect -->
      <error statusCode="404" path="/error/error404" responseMode="ExecuteURL" />
      <error statusCode="500" path="/error/error500" responseMode="ExecuteURL" />
    </httpErrors>

So it's pretty Root Relative to me.

No, I was referring to the attributes/properties in your Mvc.sitemap file and/or [MvcSiteMapNode] attributes.

However, if you do not have a <mvcSiteMapNode> defined for your error pages, or you do have them and they are configured correctly, there shouldn't be an error. If that is the case, this may be a bug.

If so, I would appreciate you providing a small demo project with this problem so I can work out what is causing it. You can either post it on GitHub or zip it and make it available for download.

Thanks for the quick responses.

Thanks!

Sure thing. Give it a few minutes for the NuGet package to be built and propagated onto NuGet gallery.
