I followed the installation, etc but I came into the following bugs. Please check the attached file.

I haven't done anything yet after the git clone and npm install. So to reproduce:

1. Run the git clone https://github.com/aws-samples/amazon-transcribe-medical-demo.git.
2. npm install
3. npm run build
4. npm start
5. Runs the app in the development mode. Open http://localhost:3000 to view it in the browser.
