Search Pattern Error since Google Scripts V8 Update

Question

Ever since google forced the update \"This project is running on our new Apps Script runtime powered by Chrome V8.\" I\'m getting the following error and I don\'t understand why

Answer 1

Possible cause(s):

• Your original rhino script is buggy, because it doesn't check the type of the argument fields[0][i] and newData[0][i].

• Empty string "" and null also throw this error.

Solution:

• Cast type and check length of the argument before feeding it to replaceText()

Snippet:

if (String(fields[0][i]).length){
  newBody.replaceText(String(fields[0][i]), String(newData[0][i]));
}
