To address a script error in an automated Google Sheet report, I would start by reviewing the error message to understand the specific issue. Next, I would check the script editor in Google Sheets to identify any recent changes or errors in the code. I would look for syntax errors, incorrect references, or logic issues. If the error isn't immediately clear, I would use the Logger.log function to add debug statements in the script, which would help track the flow and identify where the script is failing. Additionally, I would ensure that all necessary permissions are granted for the script to run. If needed, I could consult documentation or seek advice from colleagues with more experience in Google Apps Script. Once the issue is identified, I would make the necessary corrections and test the script to ensure it runs smoothly and updates the report as expected.
