byte[] in Response object for OpenApiResponseWithBody triggers an error

[grik001]

Hi,

I am not sure if everything is correct in my implementation. But it seems that when I use a byte[] in a return object I get the following error:

If I remove the byte[] array, the swagger/openapi are generated as expected.

@grik001 Thanks for the issue! The byte type is not supported at the moment.

@grik001 Hi,

I had the same issue and I resolved it by adding ByteVisitor manually to the visitor collection when initializing the document since I noticed that it was missing in the source code. It's not the perfect solution though. Hope it helps you as well.

Code example below:

public class ByteTypeVisitor : TypeVisitor
    {
        public ByteTypeVisitor(VisitorCollection visitorCollection)
            : base(visitorCollection)
        {
        }

        public override bool IsVisitable(Type type)
        {
            return IsVisitable(type, TypeCode.Byte);
        }

        public override void Visit(
            IAcceptor acceptor,
            KeyValuePair<string, Type> type,
            NamingStrategy namingStrategy,
            params Attribute[] attributes)
        {
            Visit(acceptor, name: type.Key, title: null, dataType: "string", dataFormat: "byte", attributes: attributes);
        }

        public override bool IsParameterVisitable(Type type)
        {
            return base.IsVisitable(type);
        }

        public override OpenApiSchema ParameterVisit(Type type, NamingStrategy namingStrategy)
        {
            return ParameterVisit(dataType: "string", dataFormat: "byte");
        }

        public override bool IsPayloadVisitable(Type type)
        {
            return IsVisitable(type);
        }

        public override OpenApiSchema PayloadVisit(Type type, NamingStrategy namingStrategy)
        {
            return PayloadVisit(dataType: "string", dataFormat: "byte");
        }
    }

I'll start having a look soon on the other repo: https://github.com/Azure/azure-functions-openapi-extension

Following, would like this feature as well since I have the same issue.
Thanks
