If this code works for you, the problem is the folloing incompatible
change in Org 9.3 (see etc/ORG-NEWS file in the repo):

* Version 9.3
** Incompatible changes
*** ~:file~ header argument no longer assume "file" ~:results~

The "file" ~:results~ value is now mandatory for a code block
returning a link to a file.  The ~:file~ or ~:file-ext~ header
arguments no longer imply a "file" result is expected.

Best,
