Hi ​@Kempe ,

This error usually happens when Zapier is waiting too long for Google Sheets to respond. A 160-second timeout means the zap is trying to pull or update too much data at once.

Here are some steps you can take to troubleshoot it:

Check if your sheet has too many rows, formulas, or linked cells. Large or complex sheets often cause slowdowns. Try trimming unused rows and simplifying formulas.

If you’re using “Find or Update Spreadsheet Row,” make sure the column you’re searching is indexed properly (like email or ID) and not scanning through a massive range.

Split the sheet into smaller ones if possible. Instead of working with one very large sheet, break it down by category or date range.

Add filters or conditions earlier in the zap so you’re only pulling the specific data you need, not the entire sheet.

Test the zap step by step. Run just the Google Sheets step alone to confirm how long it takes—if it hangs, the issue is in the sheet itself.

Pro tip: Zapier works best with sheets under 10k rows and without heavy formulas. If you regularly need to handle larger datasets, consider using Zapier’s Storage app, Airtable, or a database as the middle layer instead of Google Sheets.

​@Kempe  Give that a try, and if it still doesn’t work, share a screenshot of your Google Sheet and the field mapping in Zapier and zap flow, so we can take a closer look.

Hey ​@Kempe,

Can you post screenshots of Data In and Data Out as well as how each Zap step is configured for us to have more context?

Here is a helpful article for timeout in Zapier- https://help.zapier.com/hc/en-us/articles/8496246377357-Fix-timeout-errors-in-Zaps. If you are not handling large amount of data, it might be some temporary issue which will resolve on their own.

For professional/ team plans each action has a timeout limit of 30 sec while enterprise customers have a timeout limit of 120 sec. To be under these limits you may want to look into using using Looping by Zapier, Storage by Zapier or Zapier Tables and fetch less data to be under the limits. Hope it helps!

Hey ​@Kempe 👋 Did the replies from Ashar Malik Easyaiz and Sparsh help you to determine why the Zap was running into those errors?

Want to make sure this gets sorted, so please let us know whether you still need any help resolving this.
