Google Apps Script time-based trigger failing with “Error code INTERNAL”

Data Studio Data Studio Q&A

Hello, I’m looking for help with a Google Apps Script failure.

My script is named “DDC - Airtable Core Sync” and it runs from a time-based trigger. The function that failed is:

triggerAirtableSyncAndFixedStructure

The failure email says:

We're sorry, the JavaScript engine reported an unexpected error. Error code INTERNAL.

It started at 6/8/26 10:05:19 PM EST and ended at 10:07:16 PM EST.

I’m trying to understand whether this is a temporary Google Apps Script internal issue, a timeout, an API issue, or something wrong in my script. The script syncs/fixes data from Airtable into my core data structure.

What should I check first in the execution logs, and is there a common fix for this type of Error code INTERNAL on a time-based trigger?

I can share the relevant code or logs if needed.
