Generating image: Argument ($hiddenLayers) must be of type array null given

[jazithedev]

I'm trying to generate a graph

./vendor/bin/deptrac  --formatter=graphviz-image --output=./deptrac.png

and experiencing such error:

Warning: Undefined array key "hidden_layers" in phar:///my_path/vendor/qossmic/deptrac-shim/deptrac/src/Supportive/OutputFormatter/Configuration/ConfigurationGraphViz.php on line 13

Warning: Undefined array key "groups" in phar:///my_path/vendor/qossmic/deptrac-shim/deptrac/src/Supportive/OutputFormatter/Configuration/ConfigurationGraphViz.php on line 13

I'm at the newest version of Deptrac.

Here's the config:

parameters:
  paths:
    - ./src
  exclude_files:
    - 'Kernel.php'
  layers:
    - name: Application
      collectors:
        - { type: directory, regex: src/Application/.* }

    - name: Domain
      collectors:
        - { type: directory, regex: src/Domain/.* }

    - name: Infrastructure
      collectors:
        - { type: directory, regex: src/Infrastructure/.* }

  ruleset:
    Application:
      - Domain
    Domain: ~
    Infrastructure:
      - Application
      - Domain
