Docker image : latest

Issue : Unable to generate code from OpenAPI v3 documentation file. The command that i used is :

docker run --rm -v .:/app swaggerapi/swagger-codegen-cli generate \
    -i /app/openapi_hermes_v1.10.0.json \
    -l html2 \
    -o /app/output

Error that i got when running the command : 

[main] INFO io.swagger.parser.Swagger20Parser - reading from /app/openapi_hermes_v1.10.0.json
[main] INFO io.swagger.parser.Swagger20Parser - reading from /app/openapi_hermes_v1.10.0.json

Exception in thread "main" java.lang.RuntimeException: missing swagger input or config!

On Stackoverflow forum, i found that the 2.x version supports only the swagger schema.
