I built an n8n workflow where I first retrieve data from a sheet, process it to remove duplicates, then clear the entire sheet, and finally write back the cleaned data.
While implementing this, I encountered an error in the node responsible for clearing the sheet. I was advised to add a Wait node both before and after the Clear node, which resolved the issue.
I would like to understand why adding these Wait nodes fixed the problem.
The wait nodes are addressing timing constraints in the Google Sheets integration. When you clear and immediately write back, the API sometimes has internal locking or rate-limit protection—the sheet needs a moment to release the lock. The wait nodes give that breathing room. You can experiment with shorter wait periods (e.g., 500ms instead of 1s) to optimize for your specific workflow.
