I found an error in the document

[Surzace1]

it's in the example provided of the PSR HTTP Bridge section, when I am writing the code based on the example.

The error means paramt is unknow.

This is the example in the document.

Yes, that's right, in some version the parameter was renamed to requestFactory, because this name is more obvious what is required.

Thanks!
