Describe the problem/error/question
Openrouter.ai (base url amended from openai) - n8n cloud version 1.75.2 (Intel 2019 MBP macOS v15.1.1) - available models not displayed even through credentials are validated and openrouter and openai accounts are funded
What is the error message (if any)?
No models are selectable even through valid credentials for open router, there is credit on the open router and open ai accounts, the base url has been updated. Red triangle warning but no explicit error message
