Problems when injecting DLL with Node.js

Question

I am trying to inject a dll into my Node.js application but can’t progress would like to know if anyone can help me?

Application code

var edge = require('edge-js');

    var Dtef = edge.func({
        assemblyFile: 'C:/DPOS8/Bin/DPOSDRV.dll',
        typeName: 'Integer',
        methodName: 'TransacaoCartaoDebito'
    });

Error while executing

Error: Não foi possível carregar arquivo ou assembly 'file:///C:\DPOS8\Bin\DPOSDRV.dll' ou uma
de suas dependências. O módulo deveria conter um manifesto de assembly.
