I have a unusual problem which I have no idea how to solve.
I have a JSON file, where a application id is stored, namely the following:
\"app_id\": \
If you can change the JSON file contents, have you tried wrapping the application ID in quotes, like so:
"app_id": "'363924477024846'"
As clentfort has said, you're exceeding the max value for a 32bit integer (~2.1bn signed)
