Error deploying .Net Core 2.0 Web API to AWS Elastic Beanstalk

I have built my Web API using .Net Core 2.0 . Now I'm trying to deploy the project to AWS using its Elastic Beanstalk service . I also used Visual Studios AWS deployment tools .

During deployment I get the following error;

An error occurred during deployment: Part of the path 'C:\inetpub\AspNetCoreWebApps\app\appsettings.Development.json' could not be found.

I added the following section to mine .csproj;

<ItemGroup>
    <Content Update="appsettings.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </Content>
    <Content Update="appsettings.Development.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </Content>
</ItemGroup>

When building the project , I can see appsettings.jsonand appsettings.Development.jsonin my output folder. If I publish the app to my local PC, they also appear in the published directory.

I don't understand why Amazon's service is not receiving...

EDIT: So, interestingly, I created a new .Net Core 2.0 Web Api project from the Visual Studio template and tried to deploy it to AWS and it gave me the same error. However, when I create an MVC project and deploy it to AWS, everything works fine. The default settings for the Web API template seem to affect the deployment in some way...
