Description

I tried to upload a file using axios in react-native using the following sample code

const obj = {
            hello: "world"
        };

const json = JSON.stringify(obj);

const blob = new Blob([json], {
        type: 'application/json'
        });

const data = new FormData();

data.append("document", blob);

axios({
  url: 'SOME_URL',
  method: 'POST',
  headers:{...}
            },
  data: data
 })
 .then(res => console.log(res))
 .catch(res =>  console.log(res))

On react-native it is setting the content-type as "text/plain" but when I tried on the web it is setting the correct content-type as "multipart/form-data".

I tried setting Content-Type : 'multipart/form-data' but still it reverts back to text/plain in react-native.
