Error running npm-groovy-lint in Docker container: GroovyLint: Unable to start CodeNarc Server.

I am trying to run npm-groovy-lint as a Docker container in a GitLab CI pipeline (similar to CircleCI). My CI config looks something like:

groovy_lint:
  stage: lint
  image: 
    name: nvuillam/npm-groovy-lint
    entrypoint: 
      - /bin/bash
  script:
    - node -v
    - java --version
    - npm-groovy-lint --version
    - npm-groovy-lint --noserver --config ".groovylintrc.json" --failon warning --verbose

However, it fails with the following error:

$ node -v
v18.19.1
$ java --version
openjdk 17.0.10 2024-01-16
OpenJDK Runtime Environment (build 17.0.10+7-alpine-r0)

$ npm-groovy-lint --version

I tried different permutations of the command: no flags, different path, different entry point, different image version, but it was always the same issue with CodeNarc unable to start. Any guidance on this would be greatly appreciated.

@CliveUnger please can you test with latest version ?
