Google Sheets Trigger Failing to Load Sheet List in n8n Workflow

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I'm encountering an issue where the Google Sheets trigger in my n8n workflow isn't loading the sheet list, even though I've enabled both the Google Drive and Google Sheets APIs. It worked once when I manually added the link, but now I can’t select a sheet.

Below are my current settings:
• n8n version: 1.78.1
• Database (default: SQLite): default
• n8n EXECUTIONS_PROCESS setting (default: own, main): default
• Running n8n via: n8n cloud
• Operating system: Windows 11 PRO (23H2 version)

Here is my workflow configuration:

JSON
{ “nodes”: [ { “parameters”: { “pollTimes”: { “item”: [ { “mode”: “everyMinute” } ] }, “documentId”: { “__rl”: true, “value”:[Data.csv - Google Drive](https://drive.google.com/file/d/1SkTblr7rqkWfbHLk_rxiR0h-cLrlImgl/view?usp=sharing)”, “mode”: “url” }, “sheetName”: { “__rl”: true, “mode”: “list”, “value”: “” }, “options”: {} }, “type”: “n8n-nodes-base.googleSheetsTrigger”, “typeVersion”: 1, “position”: [ 0, 0 ], “id”:00754262-af72-4463-af01-b27a9b16b801”, “name”: “Google Sheets Trigger”, “credentials”: { “googleSheetsTriggerOAuth2Api”: { “id”: “wiIlLqmDK7UVuNs8”, “name”: “Google Sheets Trigger account 3 } } } ], “connections”: {}, “pinData”: {}, “meta”: { “templateCredsSetupCompleted”: true, “instanceId”: “fe7ccd31f041f454c4789c97bbfe178f380ea1a10e4df1c5c289f17c3734899c” } }

Images demonstrating the issue are included in the original post. I’m looking for suggestions on how to resolve this problem and ensure that the sheet dropdown loads correctly. Any assistance would be greatly appreciated.

Below is a list of suggestions to troubleshoot why the sheet list isn’t loading:

1. Verify the Document URL

Ensure that the URL (or documentId) you provide points to an actual Google Sheets spreadsheet. In your workflow you’re using a link that appears to reference a CSV file from Google Drive. The Google Sheets Trigger expects a valid Google Sheets file (a spreadsheet) so that it can retrieve the list of sheets. Try using a Google Sheets URL instead.

2. Re-enter or Reset the Node

Sometimes the list caches an invalid response. Open the node again on the canvas or remove the link and reinsert it. This can force n8n to re-fetch the list.

3. Confirm Credential and API Access

Since you mentioned the APIs for Google Drive and Google Sheets are enabled and the credential appears to be working (given it worked once), double-check that:

  • The Google Sheets file is shared with the service account or authorized email.
  • The OAuth2 credentials haven’t expired.
  • There are no changes to permissions on the Google Sheets file.

4. Validate Your Connection Setup

Although using n8n cloud means reverse proxy configuration is less likely to be an issue, verify your connection settings if you have a custom network configuration. When running locally (or behind a self-hosted proxy), missing websocket proxy support can sometimes lead to issues with dynamic list loading.

Next Steps

If after verifying you’re using a proper Google Sheets URL the list still doesn’t load:

  • Manually set the sheet name by switching the “sheetName” option from “list” to “manual” (if available).
  • Re-check the file permissions and sharing settings provided by Google Drive.

By confirming that the file is indeed a valid Google Sheets spreadsheet and ensuring your credentials have correct access, the dropdown for sheet names should load properly.
