As per your post, the JSON string seems to be incorrect. Because it is not ending with the required braces. So, the JSON is not incomplete and that is why the parsing is giving you the error.

If you add ""}}] This braces and quotes at the end of your JSON string, it will work. But I am wondering how you are getting this incomplete JSON from the API. If you can provide the entire response of the API, that would be more helpful but as per the JSON you have posted, I gave my answer. Please check the screenshot below.
