Hi Oscar,
Thank you for reaching out. Have you checked if the UI Keyword Planner is also returning no values for those metrics? If so, please reach out to the Google Ads Product Team
here as they will be more equipped to assist you.
If it is just an API related issue, please share your complete detailed request and response logs for the call
via Reply privately to author so that I can further investigate the issue. You can find information on enabling logging in the ReadMe of your
client library.
Regards,
Mitchell
Google Ads API Team
