On my localhost I have this error:

FatalError {fatalErrorMessage = "SqlError {sqlState = "P0001", sqlExecStatus = FatalError, sqlErrorMsg = "node_stories: ngrams are missing: {\"id\":281416,\"node_id\":74824,\"version\":10,\"ngrams_type_id\":4,\"ngrams_id\":17891334,\"ngrams_repo_element\":{\"list\": \"StopTerm\", \"size\": 1, \"children\": [\"carres d ananas\", \"morceau d\226\128\153ananas coupe\"]}}", sqlErrorDetail = "", sqlErrorHint = ""}"}

I imported an ngrams list and since then I can not add any term to it, I got such error
