Could a script be the cause of the 'Unexpected EOF' error, and if so, how do I troubleshoot it?

Yes, a faulty script that generates or manipulates JSON data can definitely cause this error. Review the script's code, particularly the sections that handle JSON reading and writing. Ensure that the script properly closes all JSON structures. You can use `JSON.stringify` in your script's debugging process to verify the structure of the JSON data it creates before writing it to a file.
