I've been banging on this for two days, no matter which angle I try to take to get Gmail connected to n8n I get "Bad request - please check your parameters"
Have tried:
My current self-hosted n8n on Railway
A new cloud n8n account
Service account
OAuth
Three different gmail accounts
I honestly can't use n8n for many automations I normally do with Zapier if I can't access Gmail (for some reason Google Sheets is no problemo).
Any guidance would be greatly appreciated.
