InputActions bug after upgrading to 1.3

I had my input working good until I upgraded to 1.3.9. I can’t no longer use InputActions since I get the error:

Could not parse input actions in JSON format from ‘Assets/Samples/PolySpatial/InputMaps/PolySpatialInputActions.inputactions’ (System.InvalidOperationException: Failed to add object of type InputActionReference. Check that the definition is in a file of the same name and that it compiles properly.

The InputSystem package was updated to 1.8.1 and apparently that’s the problem.

It’s not compiling the inputActions from the samples and it’s not compiling the ones I create.

Any idea how to fix this? Guess downgrading will work at the moment.
