Oauth access token - Intermittent "Invalid OAuth token"

Questions

Hello Everyone,

I’ve successfully created an OAuth2 API credential for Zoho (Zoho WorkDrive), and the account connection is functioning properly:

I’m working on creating a new subfolder in Zoho WorkDrive for approximately 10,000 folders. To achieve this, I’m using n8n with the following setup:

Webhook
HTTP Request to Zoho WorkDrive (read current folder)
HTTP Request to Zoho WorkDrive (create subfolder)

I’m making API requests to the webhook via Postman, using a CSV file to push the data. Each request is sent every 10 seconds.

However, after about 4,000 API calls, the workflow started failing with this error:

Upon investigation, I noticed the connection remained active. Interestingly, without any intervention, the workflow resumed on its own:

Failure started at 12:30:22

then ended at 12:40:20

For exactly 10 minutes, Zoho returned an “Invalid OAuth token” error. This is happening multiple times a day. Here is another one:

Error started at 10:17:21 and ended at 10:20:13

Does anyone have insight into why this might be happening? I’m uncertain whether this issue is related to Zoho or n8n.

n8n version: 1.71.3 (self-hosted)
Database: GCP Hosted Postgres
n8n EXECUTIONS_PROCESS setting: own
Running n8n via: GCP Kubernetes
