Sorry, for this question. I don't get the connection to claude. With OpenAI everything works fine, what did I wrong. It's possible to connect to anthropic or?
Name and Model ID, I choose: claude-3-5-sonnet-20240620

Thank you very much

I get the error: "Custom api key is incorrect. Please fix it in your profil setting."
The API work fine in my own script. I tries everything, with " and ' before and after the api-key, in the profil, in .env_local, in the model , but I still get these error. What do I am wrong? Thank you very much
