I built an experiment in RapidMiner that does the following:

1) Using the 'Search Twitter', it searches twitter for keywords/queries

2) Using 'Filter keywords', it filters the results by number of retweets greater than 1

3) Using 'Selelect Attributes', it selects only the attribute 'From-User'

4) Using 'Loop Values' with emebedded 'Get Twitter user details', I extracted the user details of all users in (3) above

5) Using the 'Append' tool, I appended all the user details into 1

 

On running the experiment, it gave an error of 'Twitter API error' at the 'Get Twitter User Details' tool.

 

Not sure how to fix it, any help will be apreciated.

 

XML code of the experiment is attached:

    Hi @m_oke,

     

    the following line in your log file explains the problem:

     

    Caused by: Server returned HTTP response code: 400 for URL: https://api.twitter.com/1.1/users/show.json?screen_name=Rebecca Lopez&include_entities=true

    The Operator "Get Twitter User Details" with the parameter name searches for the Screen name of a user.

    That is the one with @. Those do not have blanks. If you can obtain those names you can use them.

    Otherwise you can use the parameter id within "Get Twitter User Details". The id is a number and is also available from the Operator Search Twitter (Attribute: From-User-Id).

     

    An example process can be found in this community post.

     

    Best regards,

    Edin
