Hello,
We discovered that file storage's create URL feature is broken in PostgreSQL version.
I pin pointed it to "fs_simple_object__new" function in packages/file-storage/tcl/file-storage-simple-pacakge-create.tcl . It seems that "perform" is missing.
Just change
acs_object__update_last_modified(p_object_id);
to
perform acs_object__update_last_modified(p_object_id);
You need to drop the function and create it again, of course.
Best,
