I had to use .data, using .read function with debug resulted with a bug when the response already read by the debugger it returned an empty string.
I'd have to check it is not the case with the async function.

Hi @jules-ch,

Thank you for your PR. Could you please update the CHANGELOG.md to indicate that this is a breaking change and provide guidance on how users should address it?

Thanks!

[jules-ch]

Do you need me to introduce this as a BREAKING CHANGE.
Just want to wonfirm this, since the function was not returning the documented type in the first place.

I'll document it as a Breaking change for now

CI is failing because of a problem on CircleCI I think. Pipeline needs to be triggered again.
