Wrong connection for input dictionary based sentiment analysis

Hello, I downloaded the extension "Operator toolbox" to include my own sentiment dictionary. I have a folder containing multiple txt files that I want to include for sentiment analysis. I use the operator "Process documents from files". In the operator I tokenize and filter stopwords. When I want to look at the result it says "Wrong connection your connection is producing the wrong type of data."

It says:

    Hi @Kebab68,
    the input of this operator is a Collection of Documents. Please use Read Document in combination with Loop Files to get the data into the right format.
