It’s not exclusive to this update—I was on an older version of n8n and it was failing there too, so I believe it’s a change in the Toggl API or something.
Information on your n8n setup
n8n version: 1.51.1
Database (default: SQLite): Default
Running n8n via (Docker, npm, n8n cloud, desktop app): Docker
I had a look into our nodes code and it turns out we are still using toggl’s v8 API, which is now outdated. We’ll correct this as soon as possible and get back to you!
