(Has the location of this file moved on your drive or is it now in a Team or Shared Drive; Autocrat triggers will not consecutively run on files in Shared/Team Drives.Also, does this sheet have multiple Autocrat jobs on it? If yes, running many Autocrat jobs on the same sheet can get tricky if you have a lot of rows to merge or if the spreadsheet overall is very data or formula heavy. )
Otherwise yes, you are correct there are a few Google Quotas. that might be impacting your job. Autocrat is a free add-on that leverages the Google Platform to perform tasks such as running triggers and pushing out emails. Google has a 5-minute trigger run limitation, from the time the trigger is enabled, Autocrat has 5 minutes to process your whole spreadsheet, determine which rows need to be merged, create a copy of your template, merge the data on to it, and email it out for every applicable row. If this process takes longer than 5 minutes, Autocrat will time out and you could have rows that did not merge but the next Form or Time trigger that comes in should finish up rows that were left behind previously.
There is a daily total trigger runtime allowed, which depends on your account type: (90 min vs 6 hr/day)
However, if none of these pertain to your situation, please give us more details about this Autocrat set-up and the number/complexity of jobs on the account running them the more details we have on the better. We appreciate your time and support in dissecting this error. Thanks!!!
