I am trying to design analyzers for Tokenization, Case folding, Stopword removal, Word N-gram extraction and Stemming, however after writing the code it keeps popping up errors. Index name is articles and type name is article. I already tried deleting and recreating the index severally, iam very new to elasticsearch so my codes may be very wrong, please help out.
curl -H "Content-Type: application/json" -XPUT http://localhost:9200/articles/_mapping/article -d '{

It keeps bringing this error
