Hi, Thank you for reaching out to the Google Ads API support team.
The error "UNSUPPORTED_FIELD_TYPE", this means the given field type is not supported to be added directly through asset links. Kindly note that image extension as an asset is not supported in the Google Ads API as it is not included in the supported asset-based extension types mentioned in the Asset document . This is the reason why you encountered the error as well. With this, you can only add the said type of extension via feed using the Upload Image Asset implementation. You may check the document of Asset types linked to customers, campaigns, and ad groups.
