How to get product ID and variant ID with bulk editor

The page parameter is not supported in the API version you are using. If you follow the link in the error you will see:

Cursor-based pagination is supported only in version 2019-07 of the API and above. It replaces page-based pagination for the endpoints listed below.

The link contains information on how to use cursor-based pagination instead of page.

I would recommend use the program I mentioned earlier to export your IDs.
