sinon js assertion error after node is updated

Question

After updating Node to 8.1.4 , Sinon started giving unexpected assertion error. The first line does not work here

expect(spy).to.have.been.calledWith({type:'RECEIVE_INFO', status:'InProgress'})

expect(spy).to.have.been.calledWith({type : 'REQUEST_INFO'})

Here the line one does not work for some reason. But the line 2 works. All , the other dependent code is same. The same code works when we use node 7. Please help. Please let me know in case of any questions.
