Cannot write to a closed TextWriter

Hi all

I am trying to use https://github.com/unchase/Unchase.OData.Connectedservice/ to generate OData client C# code based on a metadata file.

The service is hosted on SAP S/4HANA and the metadata is in version 2.0.

Here is the content of the metadata:

The following steps show how I imported the metadata file:

As you can see on the last step I have received an error.

I also tried to import https://services.odata.org/V2/Northwind/Northwind.svc/$metadata file and it generated OData client without any error.

Best regards,
