Trying my first React Application.
I am getting the error when calling the API Gateway endpoint:
Endpoint works when I use Postman , Browser and Python Script

Error fetching session ID: Error: Failed to fetch

function App() {
  const [faceLivenessAnalysis, setFaceLivenessAnalysis] = React.useState(null)
  const [sessionId,setSessionId] = React.useState(null)
  const [loading,setLoading] = React.useState(null)

  useEffect(() => {
    const fetchCreateLiveness = async () => {
        try {
             const response = await fetch('https://xxxx-api.us-east-1.amazonaws.com/dev', {
              mode: 'no-cors'
          });
            if (!response.ok) {
                throw new Error('Failed to fetch');
            }
            const data = await response.json();
            const mockresponse= { sessionId:data.sessionId}
            setSessionId(mockresponse);
            setLoading(false);
            console.log('session:', data.sessionId);
        } catch (error) {
            console.error('Error fetching session ID:', error);
            setLoading(false);
        }
    };

    fetchCreateLiveness();
  }, []);
