How to convert or parse a Gherkin Feature FIle into JSON object using Python I have a Cucumber Gherkin file that needs to be converted into JSON object. I am using Python dictionary and json library and file object.

from pytest_bdd import scenario

Can you please clarify why this is giving an error?
