IFontResolver return buffer null

Question

I'm using PDFSharpCore to create a pdf, when I came across the problem that there are no fonts on my android device (I'm using a physical android device since emulators are not working on my computer), I googled and found this IFontResolver:

public class GenericFontResolver : IFontResolver
    {
        public string DefaultFontName => throw new NotImplementedException();

        public byte[] GetFont(string faceName)
        {
            var assembly = this.GetType().GetTypeInfo().Assembly;
            var directory = $"CartaoVisitaNFC.Fonts.{faceName}.ttf";
            var stream = assembly.GetManifestResourceStream(directory);
            
            using (var reader = new StreamReader(stream))
            {
                var bytes = default(byte[]);

                using (var ms = new MemoryStream())
                {
                    reader.BaseStream.CopyTo(ms);
                    bytes = ms.ToArray();
                }

                return bytes;
            }
        }

        public FontResolverInfo ResolveTypeface(string familyName, bool isBold, bool isItalic)
        {
            return new FontResolverInfo(familyName);
        }
    }

I already checked the "stream" and it is not getting null and using the breakpoints I identified that the error is in this line of code

using (var ms = new MemoryStream())
                {
                    reader.BaseStream.CopyTo(ms);
                    bytes = ms.ToArray();
                }

and it is returning this error System.ArgumentNullException Message=Buffer cannot be null. Parameter name: buffer

how can i solve this problem? obs: The font I'm trying to use is verdana. .net version is .netstandard2.0

IFontResolver return buffer null
