New shape length does not match original length Error (Text classification using Deep Learning-CNN)

Hi, I'm working on text classification using various type of classification algorithm to see which one has the best accuracy.

Everything was going well until I get this error message from Deep Learning-CNN Operator  "New shape length does not match original length"

My question is how do I know the dimension of the data? What is the kernel size(HxW) because it's not an image.

Thanks for your help!
