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.
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!

This is log from Mautic when I tried to create a new contract
(Select the nodes on your canvas and use the keyboard shortcuts CMD+C/CTRL+C and CMD+V/CTRL+V to copy and paste the workflow.)
