Wait for loadingFinished before requesting response body

Seems like this project is not maintained, I have used your fork directly and I can confirm that the generated har does contain responses.

@jonapgar Thanks for providing a solution to this issue, I have used your github fork directly, are you considering mainting it or even creating a separate package on npm?

Hey there! Since this functionality is important for us we've started maintaining this package over at https://github.com/auteon/puppeteer-har. The API has changed slightly and the whole thing is written in TypeScript now.
