I have created a spreadsheet for tracking projects status that sends custom notifications to people watching particular project(s). I have moved 99% of code to external library and I have referenced it within spreadsheet script. One of actions that happens every minute (trigger) is to synchronize project changes between multiple sheets within that spreadsheet. It happens that less then 10 times for 1440 executions (every minute in 24 hours) I am getting an error saying that my library is missing:
Library with identifier XXXXXXX is missing (perhaps it was deleted?)
I am using versioning on this library and all production spreadsheets have "Development Mode" set to off.
Do you know what is happening and what should I check to stop those errors being raised and sent?
