[Python] Total params: 0 , on doing model.summary() keras

model = Sequential()
model.add(Embedding(283, 100, input_length=56))
model.add(LSTM(150))
model.add(LSTM(150))
model.add(Dense(283, activation='softmax'))

model.compile(loss='categorical_crossentropy', optimizer='adam',metrics=['accuracy'])

model.summary()

I tried to build a LSTM model for text generation using a dummy dataset (had 282 unique words, checked with tokenizer), expected non zero params but the output is 0 params for each layer.
