autoencoder.fit doesnt work becaue of a ValueError

$

I don't understand what my problem is. It should work, if only because its the standard autoenoder from the tensorflow documentation.this is the error

line 64, in calldecoded = self.decoder(encoded)ValueError: Exception encountered when calling Autoencoder.call().

Invalid dtype: <property object at 0x7fb471cc1c60>

Arguments received by Autoencoder.call():• x=tf.Tensor(shape=(32, 28, 28), dtype=float32)

and this is my code

(x_train, _), (x_test, _) = fashion_mnist.load_data()x_train = x_train.astype('float32') / 255.x_test = x_test.astype('float32') / 255.print (x_train.shape)print (x_test.shape)class Autoencoder(Model):  def __init__(self, latent_dim, shape):    super(Autoencoder, self).__init__()    self.latent_dim = latent_dim    self.shape = shape    self.encoder = tf.keras.Sequential([      layers.Flatten(),      layers.Dense(latent_dim, activation='relu'),    ])    self.decoder = tf.keras.Sequential([      layers.Dense(tf.math.reduce_prod(shape), activation='sigmoid'),      layers.Reshape(shape)    ])  def call(self, x):    encoded = self.encoder(x)    print(encoded)    decoded = self.decoder(encoded)    print(decoded)    return decodedshape = x_test.shape[1:]latent_dim = 64autoencoder = Autoencoder(latent_dim, shape)autoencoder.compile(optimizer='adam', loss=losses.MeanSquaredError())autoencoder.fit(x_train, x_train,                epochs=10,                shuffle=True,                validation_data=(x_test, x_test))

I tried to change the database and also tried different shapes
