Using local middleware in a blueprint

[SSIvanov19]

Hello,
I am trying to use local middleware in a blueprint.

I defined my application as follows:

crow::App<crow::CORSHandler, AuthorisationMiddleware> app;

Then I define my blueprint

crow::Blueprint api = initApi(app);
app.register_blueprint(api);

initApi() function contains:

crow::Blueprint initApi(crow::App<crow::CORSHandler, AuthorisationMiddleware> &app)
{
	crow::Blueprint api("api");
	CROW_BP_ROUTE(api, "/users/<string>")
		.methods(crow::HTTPMethod::Delete)
		.CROW_MIDDLEWARES(app, AuthorisationMiddleware)
		([&](const crow::request& req, crow::response& res, std::string username)
			{
				// Handler continues here
				res.end();
				return;
			});

	return api;
}

But when I try to compile, I am getting the following errors:

error C2672: 'operator __surrogate_func': no matching overloaded function found
error C2783: 'void crow::detail::handler_call_bridge<crow::TaggedRule<crow::black_magic::single_tag_to_type<4>::type>,crow::Crow<crow::CORSHandler,AuthorisationMiddleware> &,AuthorisationMiddleware>::operator ()(F &&)': could not deduce template argument for 'F'

I tried to recreate this but got a different error:

error: ‘crow::Crow<AuthorisationMiddleware>&’ is not a class, struct, or union type

I fixed that by using the middlewares() method directly instead of CROW_MIDDLEWARES (the line was .middlewares<crow::App<AuthorisationMiddleware>, AuthorisationMiddleware>())

Thanks for the reply!
When I use the method instead of the macro, it works!
