Files not being attached to POST request (axios) while sending with Postman works
Solution 1:
Your "file" is in fact a FileList because you accept multiple files
You should extract them one by one:
dataArray.append("datafiles", uploadFile);
should be
// uploadFile is an HTML input element: <input type="file" id="myfileinput" multiple>
// loop through files
for (let i = 0; i < uploadFile.length; i++) {
const file = uploadFile.item(i);
dataArray.append("file" + i, file);
}
