"saveurl" dose not work

I tried the Show editor with the URL obtained with the following snippet, but the request is not sent to saveurl.

  1. <form method="POST" action="https://show.zoho.com/show/remotedoc.im" target="_self" accept-charset="UTF-8">
  2.     <input type="hidden" name="apikey" value="MY API KEY">
  3.     <input type="hidden" name="output" value="url">
  4.     <input type="hidden" name="mode" value="normaledit">
  5.     <input type="hidden" name="filename" value="Untitled">
  6.     <input type="hidden" name="lang" value="en">
  7.     <input type="hidden" name="id" value="1234">
  8.     <input type="hidden" name="format" value="pptx">
  9.     <input type="hidden" name="saveurl" value="https://example.com/mypath/save.php">
  10.     <input type="submit" name="submit" value="Open">
  11. </form>

The save command has been sent to https://docs.zoho.com/show/r_documentoperation, but the response is empty.

But Writer and Sheet editors are OK for the same endpoint.

Thank you for your support.
