I have added the open ai key in the env file and getting it in config as "'apikey' => env('OPENAI_API_KEY')," but when i runs the command to create tread by this package i get the error "local.ERROR: Incorrect API key provided: ''. You can find your API key at https://platform.openai.com/account/api-keys. {"exception":"[object] (OpenAI\Exceptions\ErrorException(code: 0): Incorrect API key provided: ''.
