File uploaded using postman shows undefined in request body

Question

I am trying to create a multipart/form-data request in postman as below

However, while sending this request, I could see postman showing undefined for the fileToUpload

Any help on this issue is much appreciated.

Answer 1

In my case it is showing undefined when I'm attaching a file to the multipart but the file is sent successfully.

I checked it because I used a mock endpoint to inspect the request payload being sent.

You can use any similar tool to check it:

• HttpToolkit (what I used)
• Requestbin
• Wireshark

Or any network sniffer.
