[SOLVED] Setup Metarank (for recommendation) with its one minute setup tutorial fails with validation error

Setup Metarank (for recommendation) with its one minute setup tutorial fails with validation error

I was following Metarank documentation and tried to get it up and running with its sample data which I couldn't.

since it is the tutorial and I have no clue to how to fix it, I'm eager to know what is the problem.

This is the course of actions I took:

downloaded data set from here as the docs says
downloaded data set from here as the docs says
run this docker command:

docker run -i -t -p 8080:8080 -v ./metarank:/opt/metarank metarank/metarank:latest standalone --config config.yml --data events.jsonl.gz

but I got the following error:
