Keras.js Error: [Model] Model configuration does not contain any layers.

I tried to run keras model on a browser using keras.js , but I got the following error while loading it

Error: [Model] Model configuration does not contain any layer
The kera model is

from keras.models import Sequential
from keras.layers import Dense, LSTM, InputLayer, Bidirectional, TimeDistributed, Embedding, Activation
from keras.optimizers import Adam
model = Sequential()
model.add(InputLayer(input_shape=(MAX_LENGTH, )))
model.add(Embedding(len(word2index), 128))
model.add(Bidirectional(LSTM(256, return_sequences=True)))
model.add(TimeDistributed(Dense(len(tag2index))))
model.add(Activation('softmax'))
 
model.compile(loss='categorical_crossentropy',
              optimizer=Adam(0.001),
              metrics=['accuracy', ignore_class_accuracy(0)])
 
model.summary()

Then I have converted with encoder.py as

python encoder.py model.hdf5
And load it with keras.js as

cconst model= new KerasJS.Model({
        filepath: {
          model: 'model.json',
          weights: 'model_weights.buf',
          metadata: 'model_metadata.json'
        },

          gpu: false
        })

I have tried with keras version 2.2.4 , 2.1.4, 2.2.2, 2.1.5 and 2.1.4 .

Any help would be appreciated.

2.0.6 version removed this error for me
