Codesandbox Case (Bug Reports)
https://codesandbox.io/s/primereact-test-forked-hszlq

Current behavior
I've upgraded from version 5.0.2 to primereact 6.0.2 and a reference I've set in an inputtext component is no longer working, as you can see in codesandbox. It fires the error below in console:

Warning: Failed prop type: Invalid prop `forwardRef` of type `object` supplied to `InputTextComponent`, expected `function`.    in InputTextComponent (created by ForwardRef)

    in ForwardRef (created by App)

    in App

Expected behavior
I was expecting this reference to work in order to be able to focus an input after setstate was fired. It was properly working before the upgrade, now the reference is missing and this error breakes all my Jest tests.

Minimal reproduction of the problem with instructions
Defining a reference using something like referenceVariable = createRef() and adding a property ref={referenceVariable} will fire up this error in primereact 6.0.2. I've tried it among different node versions, like 10, 14 and 15.

Please tell us about your environment:
I'm running MacOS BigSur, with Yarn, Webpack and ruby on rails and Puma webserver. But this error was easily reproduced in codesandbox.
