Error when running basic example: Unexpected end of JSON input

[dan-mk]

I've encountered an issue when attempting to run the basic example provided in the README. The process ends with some error messages, and I'm unable to proceed. I've installed it locally and within Docker afterwards, but I've got the same results.

Here is the output I received:

This is my Dockerfile:

FROM node:14.16.1

WORKDIR /usr/src/app
RUN git clone https://github.com/ExpoSEJS/ExpoSE.git .
RUN ./install

And this is my docker-compose.yml:

version: '3.8'

services:
  expose:
    build: .
    container_name: my-expose-container
    command: ["./expoSE", "./tests/numbers/infoflow"]

I'm unsure how to proceed with troubleshooting this issue.

Any guidance or fix you can provide would be greatly appreciated.

Silly me. I was trying to Dockerize the code myself because I didn't realize how hard it was, and most importantly, I didn't realize there's already a Dockerfile in the repo. Setting EXPOSE_PRINT_PATHS=1 really showed me how deep the problem was hahaha. Thanks @JJK96.
