Browser Link: Failed to invoke return value callback:

我已将我的应用程序配置如下：

.csproj配置：

    <PackageReference Include="AutoMapper.Extensions.Microsoft.DependencyInjection" Version="1.2.0" />

</ItemGroup>

<Target Name="PrepublishScript" BeforeTargets="PrepareForPublish">
    <Exec Command="bower install" />
    <Exec Command="dotnet bundle" />
</Target>

在Configure方法的Startup.cs文件中,我调用了app.UseBrowserLink();.

UPDATE

似乎错误与* .css文件有关.如果我删除所有CSS链接,我只会收到以下错误：

Browser Link: Failed to invoke return value callback:
TypeError: Cannot read property 'files' of null
