ERR_SCRIPT_TIMEOUT on Airtable: Script execution time exceeded / Limit 30s. Root cause: Unoptimized await fetch commands inside loops inside the Airtable scripting block Step 1: Kill Procedural Loops. Replace for (let record of records) { await table.updateRecordAsync(...) } structures entirely. Step 2: Leverage Batch Operations. Utilize table.updateRecordsAsync() (plural) which accepts an array of up to 50 modified records in a single asynchronous call. Step 3: Apply Asynchronous Processing. Wrap independent external fetch API queries inside a Promise.all() wrapper to fire calls in parallel rather than sequencing them back-to-back.
