Chapter 1 example problem MountainCarContinous environment and the DiscretePolicy example code throw the following error:

ValueError: in converted code:

ValueError: The last dimension of the inputs to `Dense` should be defined. Found `None`.

I double checked and typed the code per the book examples - seems to be in class Brain call function. Any idea?
