API occasionally returns invalid json

[netllama]

The API occasionally returns invalid json, although I'm not able to manually reproduce the problem. For example, this query:
http://theapache64.cf:8080/movie_db/search?keyword=Tera%20Intezaar

usually returns this valid data:

{"data":{"plot":"A woman sets out to uncover how her lover went missing.","year":"2017","imdb_id":"tt5784852","director":"Raajeev Walia","name":"Tera Intezaar","rating":"3.6","genre":"Romance,Thriller","poster_url":"https://images-na.ssl-images-amazon.com/images/M/MV5BOWRhMWE5NzgtMGEzNS00YjM2LWE4ZTAtZWQ4MDY3MDVkMTQxXkEyXkFqcGdeQXVyNjQ2MjQ5NzM@._V1_UY268_CR4,0,182,268_AL_.jpg","stars":"Sunny Leone, Gauhar Khan, Arbaaz Khan, Sudha Chandran"},"error_code":0,"error":false,"message":"Movie found"}

However, occasionally, it will return this invalid json (note there are 2 json blobs appended together):

{"data":{"plot":"After being told that their children never existed, a man and woman soon discover there is a much bigger enemy at work.","year":"2004","imdb_id":"tt0356618","director":"Joseph Ruben","name":"The Forgotten","rating":"5.8","genre":"Drama,Horror,Mystery","poster_url":"https://images-na.ssl-images-amazon.com/images/M/MV5BMjAwMjIyNjU4NV5BMl5BanBnXkFtZTcwNjE3NjYyMQ@@._V1_UX182_CR0,0,182,268_AL_.jpg","stars":"Julianne Moore, Dominic West, Christopher Kovaleski, Matthew Pleszewicz"},"error_code":0,"error":false,"message":"Movie found"}{"data":{"plot":"A woman sets out to uncover how her lover went missing.","year":"2017","imdb_id":"tt5784852","director":"Raajeev Walia","name":"Tera Intezaar","rating":"3.6","genre":"Romance,Thriller","poster_url":"https://images-na.ssl-images-amazon.com/images/M/MV5BOWRhMWE5NzgtMGEzNS00YjM2LWE4ZTAtZWQ4MDY3MDVkMTQxXkEyXkFqcGdeQXVyNjQ2MjQ5NzM@._V1_UY268_CR4,0,182,268_AL_.jpg","stars":"Sunny Leone, Gauhar Khan, Arbaaz Khan, Sudha Chandran"},"error_code":0,"error":false,"message":"Movie found"}
