Google Apps Script Debugging

Hello, I used ChatGPT to help me create a script on Google Apps Script then when a new line is added to Google Sheets, a new customer is created on QuickBooks, but I'm running into some issues when linking and using tokens. Will pay to have someone share screens and call me for 20-30 minutes to help me with it.

To be approved say Pineapple, looking for someone to help me right now.
