How do I resolve the MulterError that states "Unexpected field"?

The code block uses the Express and Multer packages to configure a REST API endpoint '/importQuiz' that allows users to upload a single file and pass it to a controller called quizController. However, the API is throwing an error 'MulterError: Unexpected field' when posting data to 'http://localhost:3000/importQuiz'.

This error indicates that Multer is receiving a field that it is not expecting. In the provided code, Multer is expecting a file with field name 'file' and is configured using upload.single('file'). Therefore, ensure that you are creating a form in your frontend with the fieldname 'file' for the file that you want to upload. Also, ensure that the method of the form is POST and the enctype attribute is set to multipart/form-data.
