Issue with a Huge JSON parsing

I currently am having issues parsing a huge JSON string. I'm not sure why it's not being parsed completely. Is there a way to get parsing errores? (I know that when a filed was not able to be parse it gets returns as null)

No files, tests, or parser entry points are named. Start by reproducing the incomplete parsing with the reported huge JSON string and inspect the library's parsing and error-handling paths. Done means the input is fully parsed or a useful parsing error identifies the failing field.
