We are attempting to build a Rest to sFTP interface in CA API Gateway. We have created a policy to accept multi-part requests. The file sizes may go up to 1 GB. We tried testing the service with files of different sizes. We were successful only for 400MB files. Files much larger return good response, but when we check the file in FTP server, the file is created but empty. The file size is zero bytes. The Gateway logs show no error.
We are thinking if some kind of timeout is happening before the file is completely transferred, But again gateway is not throwing any error.
