Unable to get this "tagging unanswered email" script to work - google-apps-script

Question

The following is a script that I found online to tag all the unanswered emails. It works for one of my gmail accounts, however when I shared it to another account and run it, it returns nothing every single time, even though there are unanswered emails within that time range. I then tried copy and paste the codes into a new project, however still wouldn't work.
Anyone has any ideas?
Thanks in advance!
/*
* This script goes through your Gmail Inbox and finds recent emails where you
* were the last respondent. It applies a nice label to them, so you can
* see them in Priority Inbox or do something else.
*
* To remove and ignore an email thread, just remove the unrespondedLabel and
* apply the ignoreLabel.
*
* This is most effective when paired with a time-based script trigger.

The Gmail search operator "older_than" does not support decimals, so you cannot use "0.125" in this case. Make sure you use an integer number/day. The script will not return errors, but the search will not work. More info about the Gmail search operators at https://support.google.com/mail/answer/7190?hl=en
