Request that triggered auth fails after successful authentication

[vdayanand]

Request that triggered auth fails even after authentication is successful. Subsequent Pkg requests were successful.
Example:

julia> using Pkg

julia> Pkg.Registry.update()
   Updating registry at `~/projects/testdepot/registries/General`
Authentication required: please authenticate in browser.
The authentication page should open in your browser automatically, but you may need to switch to the opened window or tab. If the authentication page is not automatically opened, you can authenticate by manually opening the following URL: https://juliahub.com/auth/response?a1c2d3bd5f4d6bbe54f70365ce2e1d5d
[ Info: Authentication successful.

I think that's due to a bug in the readme. Can you try

# create a new anonymous module for the init code
Base.eval(Module(), quote
    using PkgAuthentication, Pkg

    SERVER = string(Pkg.pkg_server())

    function authenticate(url, svr, err)
        ret = PkgAuthentication.authenticate(string(svr, "/auth"), tries = 3)
        if ret isa PkgAuthentication.Success
            @info "Authentication successful."
        else
            @error "Failed to authenticate to $(svr)." exception=ret
        end
        return true, true
    end

    function register_auth_handler(pkgserver::Union{Regex, AbstractString})
        return Pkg.PlatformEngines.register_auth_error_handler(pkgserver, authenticate)
    end

    if PkgAuthentication.is_new_auth_mechanism()
        register_auth_handler(SERVER)
    else
        # old Julia versions don't support auth hooks, so let's authenticate now and be done with it
        authenticate(SERVER)
    end
end)

instead?

Yes, that works!
