error in sentiment stanford_by()

[sadettindemirel]

I have an error when using sentiment stanford_by () on rows of tweets. The thing is that when I tried the same code on 1000 rows of tweets, it worked flawlessly but later tried on 9K tweets, I got the error below. I did not clean the text before running the command and the object I work is data frame format. What am I doing wrong here?

error

Error in `[.data.table`(sent_dat[, list(sentences = unlist(sentences)), : 
Supplied 19238 items to be assigned to 19239 items of column 'sentiment'.
 If you wish to 'recycle' the RHS please use rep() to make this intent clear to readers of your code.
