Processing string input in tensorflow model

I want to make some simple string operations within the keras model such that it can be end-to-end.

def get_model_para_pure():      para = keras.Input(shape=(1, ), dtype="string", name='para')       para_lower = tf.strings.lower(para)      shingles = tf.strings.split(para_lower)      ...  

however, it raises the error:

Tensor conversion requested dtype int32 for Tensor with dtype int64: <tf.Tensor 'Cumsum_5:0' shape=(None,) dtype=int64>

How can I implement these operations within a model.
