    The problem is inside your Loop Collection operator because it is not returning any outputs.  You will need to open that up and see what is causing the problem.  Perhaps you are not actually delivering a collection for it to loop over?

    hi @Mohamad1367,

    As said in your other thread, you have to put your text processing steps INSIDE the Loop Collection operator.
    Thus put your Filter Stopwords operator  INSIDE the Loop Collection operator.

    Hope this helps,

    Regards,
