OPENAI_API_KEY="this is wrong"; chatblade test
openai.error.AuthenticationError: Incorrect API key provided: this is *rong. You can find your API key at https://platform.openai.com/account/api-keys.
if you run
echo $OPENAI_API_KEY
you should see your key which starts with sk-......... If not thats where your issue is
