Error when writing data to Excel using 'Documents to data'

Hello, I am doing my first Rapidminer project and I am experiencing an issue when trying to gather my data in an Excel file. I have Excel data of Tweets that I analyze using the Aylien Analyze Sentiment extension. This is no issue, however I am not able to transfer this sentiment data to an Excel sheet. I tried the 'documents to data' operator, but it gives my the error message depicted below. The entire process and XML process is displayed below. Does anyone know why I cant get the data to Excel using the documents to data operator? Is there maybe another way to gather the sentiment data in an Excel sheet?

    Hi @h_jernstrom,


    Simply, remove the Documents to Data operator and connect

    directly Analyze Sentiment operator to the Write Excel operator.

    @lionelderkrikor Thanks for your help! I did initially try this, but I got another error message. The 'write Excel' operator says the following: Mandatory input missing at port Write Excel.input. Is this due to the file format that the 'write Excel' operator expects to receive?

    @h_jernstrom that error leads me to believe that you didn't fill out the parameters in your Write Excel operator. Make sure you set a filename and path.

    @Thomas_Ott Thanks for your reply. I actually just now ran it despite the error message, and I successfully got the Excel output that I required, so I guess the error message could be ignored. Issue resvoled, thanks!
