"request" is null for Markdown to PDF

[smfelsher]

I am running the full image of Stirling-PDF in a Docker container, using a simple Markdown file as an example.

# Heading 1

Some text.

I get the following stack trace when I use the Markdown to PDF tool with the above Markdown file.

For reference, here is my docker-compose.yaml

name: stirling-pdf

services:
  stirling-pdf:
    image: frooodle/s-pdf:0.25.1
    container_name: stirling-pdf
    # No need to export ports since this will reside behind a reverse-proxy.
    # ports:
    #   - "8080:8080"
    environment:
      # Disable login feature.
      - DOCKER_ENABLE_SECURITY=false
      # Download calibre to enable PDF to/from book and advanced HTML
      # conversion. 
      - INSTALL_BOOK_AND_ADVANCED_HTML_OPS=true
      - LANGS=en_US
    volumes:
      - ./configs:/configs

networks:
  default:
    name: stirling-pdf-network

Any help would be greatly appreciated.

@Frooodle I see that you committed some fixes, so I downloaded frooodle/s-pdf:alpha and tried Markdown to PDF and it was successful this time.

I'm going to test some of my other Markdown files.

Thank you for the updates!

I tested a few other Markdown files, all converted to PDF!

In latest release now :)
