Remote utility return OK but no image is captured when shooting RAW+JPEG

[serg3y]

When shooting RAW + Large Fine JPEG the command: http://localhost:5513/?SLC=Capture correctly returns: RAW+JPG capture in live view not supported

However the commands: http://localhost:5513/?SLC=Do&param1=CaptureAll and http://localhost:5513/?SLC=CaptureNoAf returns: OK but no image is captured.
