Hi,
Thank you for reaching out to Google Ads API team.
Based on our documentation, any bidding strategy is defined by a single bidding scheme that matches its type and contains the relevant bids. Furthermore, this documentation states that the scheme field can only be one of the following: enhancedCpc, maximizeConversionValue, maximizeConversions, targetCpa, targetImpressionShare, targetRoas, targetSpend. With this, you will need to specify a scheme when creating a bidding strategy in order to avoid encountering the error.
For MANUAL_CPV value, can you please confirm if it's possible to create a bidding strategy of this type in the Google Ads UI? If yes, kindly provide an uncropped screenshot so we can further investigate and assist you on this. You may provide it to us via Reply privately to author option.
