Describe the problem/error/question
Hello, I’m using a self-hosted n8n instance (version 1.1.1) deployed with docker-compose. I’ve successfully set up OAuth2 authentication with Mautic, and I attempted to create a test workflow. However, I encountered the following error. I’ve been trying to troubleshoot this issue, but I haven’t been able to find a solution yet.
What is the error message (if any)?
ERROR: The service was not able to process your request
Looks like I encountered an error (error #500). If I do it again, please report me to the system administrator!
