JSON - Exception in server tick loop

If you find your server not starting up with the following error:
java.lang.NullPointerException: Exception in server tick loop at net.minecraft.server.v1_13_R3.JsonList.load(JsonList.java:171)

This means there is an issue with one of your ops.json/whitelist.json files.
To fix this, do the following:
1. Stop your server
2. Access your servers files using FTP and delete the ops.json, whitelist.json and usercache.json files
3. Start your server
