TypeError: Converting circular structure to JSON

[kirilldev]

I am using jest-cucumber with an angular 6 project. There is a problem that if an error appears on template side angular generates an error object with a circular structure.

Later when ScenarioResultFileOperations.saveScenarioResult is called I am getting an error.

TypeError: Converting circular structure to JSON

To fix the problem, instead of JSON.stringify we need to use something that can handle circular dependencies.
