Google Sheets TypeError: Cannot read property 'toString'

When using a Google Apps Script in Google Sheets, the following error occurs:
TypeError: Cannot read property 'toString' of undefined
The error is occurring intermittently on this line of code:
var DTE = DataToEncode.toString();

This error occurs in older versions of the Google Sheets Barcode Generator.

Best Answer

This error can be confusing because sometimes the code runs without error. To resolve the problem, append "" to the variable instead of using toString, for example, change:
var DTE = DataToEncode.toString();
To:
var DTE = "" + DataToEncode;
