I try to post a file with a filesize of 4GB to a REST API.
Instead of uploading a file with this size, cURL POSTs a file with Content-Length: 0.
curl -v -i -d @"/work/large.png" -H "Transfer-Encoding: chunked" http://localhost:8080/files
* Adding handle: conn: 0x7fcafc00aa00
* Adding handle: send: 0
* Adding handle: recv: 0
* Curl_addHandleToPipeline: length: 1
* - Conn 0 (0x7fcafc00aa00) send_pipe: 1, recv_pipe: 0
* About to connect() to localhost port 8080 (#0)
* Trying localhost...
* Connected to localhost (localhost) port 8080 (#0)

Using files with a smaller size will work as expected.

Why does the upload fail? And, how to correctly upload such a file?
Cheers.
To upload large binary files using CURL you'll need to use --data-binary flag.
In my case it was:
curl -X PUT --data-binary @big-file.iso https://example.com
Note: this is really an extended version of @KarlC comment, which actually is the proper answer.
