I have a service that I’m developing … takes some image files and converts the to a PDF.

If I send only ONE file on the request, spring errors out with a `Content type '' not supported` error.

If I send TWO files on the request, it works fine.

The service is written in Java and the parameter is  
`@RequestBody final List<MultipartFile> imageFileList`

It seems like this should work, but maybe I’m missing something obvious?

Thanks!

David

Some additional information…

- If I remove all files from the request, attach a new local file, and send the request … it works correctly. I get that one file sent to my server.
- If I shut down postman, start it up again, and send the same request, the file is not sent.
- If I add a new local file to the request and send it, only the new file is sent.
- If I restart postman again, and send the request, no files are sent.
- If I add a third file to the request and send it, only the new file is sent.
