Resolved empty export file after moving templates from J3 to J4 site

I moved from J3 to a fresh J4 site.
I exported and imported all Templates, and matched all config settings from the J3 site.
When I run a Template (Google merchant feeds), the file is not placed in the specified folder on the server. I tested to download the file, but then no file is downloaded.
The logs shows that records are processed though. Can you help?
