KERAS network Learner

I am getting the following Error while executing KNIME nework Learner, please help

Execute failed: An error occurred while creating the Keras network from its layer specifications. Details: Tensors are unhashable (this tensor: KerasTensor(typespec=TensorSpec(shape=(1, 28, 28, 1), dtype=tf.float32, name=‘input1’), name=‘input1’, description=“created by layer ‘input1’”)). Instead, use tensor.ref() as the key.
