HttpRequest.GetBufferlessInputStream not supported

Question

Running an MVC5 application I get this error when attempting to POST back to my controller.

I is happening during the EnsureFiles() method, but I'm not trying to load any files at all.

Here is the entire stack traces

My form is embarrassingly simple

@using (Html.BeginForm())
{
<div class="form-group">
    In order to continue you must change your password.
</div>

<div class="form-group">
    @Html.LabelFor(x=> Model.OldPassword)
    @Html.TextBoxFor(x=> Model.OldPassword)
</div>

<div class="form-group">
    @Html.LabelFor(x => Model.NewPassword)
    @Html.TextBoxFor(x => Model.NewPassword)
</div>

<div class="form-group">
    @Html.LabelFor(x => Model.NewPasswordConfirm)
    @Html.TextBoxFor(x => Model.NewPasswordConfirm)
</div>

<div class="form-group">
    <input type="submit" class="btn btn-primary" value="Submit" /> 
    <input type="reset" class="btn btn-danger" value="Cancel" />
</div>


}

Has anyone encountered this problem before. I got a couple of hits on the internet, but nothing that worked.

Answer 1

answer to this was turning off HttpLogging in Thinktecture IdSrv.

LoggingOptions = new LoggingOptions
{
  **EnableHttpLogging = false**,
  EnableWebApiDiagnostics = true,
  IncludeSensitiveDataInLogs = true,
  WebApiDiagnosticsIsVerbose = true,
},

I also got this error when adding Azure Active Directory authentication to an MVC web app that previously had no authentication.

When I moved the code below in Startup.cs from after the MVC and Web API configuration code to before it, the exception stopped occurring.

    // Microsoft Azure Active Directory
    app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);
    app.UseCookieAuthentication(new CookieAuthenticationOptions());
    app.UseOpenIdConnectAuthentication(
        new OpenIdConnectAuthenticationOptions
        {
            ClientId = appSettings.IdaClientId,
            Authority = appSettings.IdaAuthority,
            PostLogoutRedirectUri = appSettings.IdaPostLogoutRedirectUri
        });
