;Authorization failed - please check your credentials; this is the error that i get when trying to use openrouter with the openai node, yes I have added the openrouter API key, added the base URL 'https://openrouter.ai/api/v1', and the model is set to gpt-4o-mini, just the default. also when I click on 'chat' at the bottom, it just freezes the website, yes I am a noob, should I be self hosting to stop the freezing or something ?
