Error - "Worker exited with exit code 1 (signal = null)"

If you encounter the error message "Worker exited with exit code 1 (signal = null)" while working with Google Sheets, the most likely cause is an overloaded spreadsheet.

Possible Causes:

• The spreadsheet contains too many rows or columns filled with data.

• Excessive formulas, conditional formatting, or scripts running in the background.

• Google Sheets hitting its cell limit (10 million cells per sheet).

How to Fix It:

1. Delete unnecessary data – Remove unused rows, columns, or sheets.

2. Optimize formulas – Reduce complex calculations that may slow down execution.

3. Split large datasets – If possible, break the data into multiple smaller sheets.

4. Re-run the flow – After cleaning up the spreadsheet, try executing the flow again.

By reducing the spreadsheet’s size and complexity, you can prevent this error and improve performance.
