MultipartFile is empty during rest api POST of Javascript file upload

I am using React JS to upload a file. This is the file array object i am trying to send as a POST request:

I am trying to submit a POST request via axios:

The file i am sending is not empty: 

But as soon as the debugged code reaches the back-end, (REST API) the MultipartFile[] is empty 

I wonder why.. Maybe i am missing some configuration here? Please help! Thank you!

#reactjs #rest
