How to Read Large JSON file in R?

is it the exact same error ? Did you try in a clean environment ? It is easier if we have the exact command you run before error and not much. Also it is better with a reprex.

On the web, your error is associated to rjson and big json file.
You can also try to isolate where it comes from exactly (use traceback() to help), and if it is really from the rjson :package: try to contact the developer.
