Please rewrite the script completely and follow best ServiceNow's best practices.
Add a more meaningful description and how to use it.
Don't mix it with Flow Designer without explaining how to utilize it there.

Sorry, but that script is full of issues and makes no sense at all. I don't know where to start and in the end I cannot rewrite everything for you.

However, at least one important hint. The code line "child.parent_incident.update()" will not work. If you want to update the parent record you have to load an individual instance, for example with "getRefRecord()"

And also "hello" loggings do not provide any value and spam the syslog table!
