Bug: Building an image fails

[cheetahbyte]

Hello, i have the problem that i can't build images with dockerode.

My Code:

client.buildImage(
  "./Dockerfile",
  {
    t: "test"
  },
  function (err, stream) {
    if (err) console.error(err);

    console.log(stream);
  }
);

My Dockerfile:

FROM alpine:latest
WORKDIR /app
COPY test.sh .
ENTRYPOINT ["sh"]
CMD ["test.sh"]

Error:

Error: (HTTP code 500) server error - unexpected EOF 
    at /home/cheetah/Schreibtisch/test.dockerapi/node_modules/docker-modem/lib/modem.js:324:17

There was a similar error before (#5), but I did not use any unusual characters.

I look forward to an answer, and to the solution of the problem ^^
