docker run --rm --network="host" -v "${PWD}:/local" --user $UID:$UID openapitools/openapi-generator-cli:latest generate -i /local/openapi.json -o /local/out/python-experimental -g python-experimental --verbose
on an openapi description, the python-experimental code generator would throw
Exception in thread "main" java.lang.NullPointerException
