Cortex Analyzers return JSON error when run

Start by reviewing the Docker Compose configuration and the analyzer entry point at /worker/VirusTotal/virustotal.py, then follow initialization into cortexutils/worker.py where stdin is parsed. Reproduce the analyzer run and verify what input reaches the worker; done means the analyzer no longer fails with the reported JSONDecodeError.

Problem Description

I'm using docker and docker-compose, and I installed the Virtustotal_GetReport_3_1 but when I run it returns me a JSON error.

This is my docker-compose cortex cfg:

cortex.local:
    image: thehiveproject/cortex:latest
    container_name: cortex
    restart: unless-stopped
    environment:
      - job_directory=/opt/cortex/jobs
      - docker_job_directory=/tmp/cortex-jobs
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /tmp/cortex-jobs:/tmp/cortex-jobs
      - ./cortex/logs:/var/log/cortex
      - ./cortex/application.conf:/cortex/application.conf
    depends_on:
      - elasticsearch
    ports:
      - "0.0.0.0:9001:9001"
