Write dependency graph is not working or is taking too much time

My Environment: Image Inspection

My phpda.yml: Basically from the README.md

mode: 'usage'
source: './api'
filePattern: '*.php'
ignore: 'tests'
formatter: 'PhpDA\Writer\Strategy\Svg'
target: './phpda.svg'
groupLength: 1
visitor:
  - PhpDA\Parser\Visitor\TagCollector
  - PhpDA\Parser\Visitor\SuperglobalCollector
visitorOptions:
  PhpDA\Parser\Visitor\Required\DeclaredNamespaceCollector: {minDepth: 2, sliceLength: 2}
  PhpDA\Parser\Visitor\Required\MetaNamespaceCollector: {minDepth: 2, sliceLength: 2}
  PhpDA\Parser\Visitor\Required\UsedNamespaceCollector: {minDepth: 2, sliceLength: 2}
  PhpDA\Parser\Visitor\TagCollector: {minDepth: 2, sliceLength: 2}

When I run this command:

docker run --rm -v "%cd%":/app mamuz/phpda

Actual behavior: Output of following, with the cursor blinking at the end. Remains on that state still after an hour.

Write dependency graph to /app/./phpda.svg

Expected behavior: svg should be generated and the console should report its progress and finally a success or detailed error message.
