Error when training with Docker

Rasa Open Source
1

Whenever I run the train command using docker:

docker run --rm -v `pwd`:/app rasa/rasa train --domain config/domain.yml --data data --out models

I get the following error:

FileNotFoundError: [Errno 2] No such file or directory: 'data/nlu/company.json'

But I am mapping the data folder, and it does contains the directory nlu along with the company.json.

My directory is as follows:

rasa

Inside the directory smalltalk I have some *.md training data files. If I remove the company.json file, I can train the model but whenever I add a *.json file it just throw the error.
