Problem with 'Improvise a Jazz Solo with an LSTM Network

While coding djmodel , I get the following error:

Test failed at index 1
Expected value

[‘Lambda’, (None, 90), 0]

does not match the input value:

[‘TensorFlowOpLayer’, [(None, 90)], 0]

I can not proceed further. Please suggest a solution. Thanks

Do not use a Lambda function in this exercise.

Hey All:
Please help. I’m not using Lambda in slicing x but I’m still getting this same error. I have no idea what’s going on.
