This error is indicating that the value you're sending in the "Dropbox-API-Arg" header isn't valid JSON. In your code, you're setting "Dropbox-API-Arg" to "response.data.entries[i].id", which isn't JSON. It's just a string with the ID for a file.
You can see an example of what this is supposed to be in the documentation for /2/files/get_thumbnail. You probably mean to do something like this:
'Dropbox-API-Arg': JSON.stringify({"path": response.data.entries[i].id})

Exactly what you do with that is up to you. For example, you may wish to save that somewhere, or display it to the user, etc.
