API engin error

Mehdi77Mehdi77 Member Posts: 1 Newbie
I am working with RapidMiner for restaurant sentiment analysis. The error containing API engine error Expected a `:` after a key at 111 [character 112 line 1] appears whenever I run the software after using the sentiment analysis instruction. I am worn out of that. Could you help me why it happens and how I can solve this issue?

    I am getting the same error. I am using MeaningCloud sentiment analysis operator to process data from Twitter. It seems that it hasnt loaded any sentiment models on the sentiment analysis operators - as you see on the screenshot the sentiment model field is empty and it doesnt give you any options, the same with User dictionaries. I have properly installed the licence key.
