TypeError: Cannot convert 1 to EagerTensor of dtype string

Getting below error when trying Quickstart example.

OSX 14.2.1
python 3.12
tensorflow 2.16.2
tensorflow-recommenders 0.7.3
tensorflow-datasets 4.9.6
keras 3.4.1

I've overcome this by changing the keras code like below - "site-packages/keras/src/initializers/constant_initializers.py", line 35

    def __call__(self, shape, dtype=None):
        dtype = standardize_dtype(dtype)
        return ops.cast(self.value, dtype=dtype) if dtype == "string" else ops.cast(self.value, dtype=dtype) * ops.ones(
            shape=shape, dtype=dtype
        )

Not sure how this code has been this way and worked but the Quickstart example is not working with this code for sure.
