Oracle Set Transaction: Inconsistent Behavior with Missing AssetPrice Field

[ObiajuluM]

The XRPL documentation states: "Token pairs in the transaction with a missing AssetPrice field delete corresponding token pairs in the object."

However, when creating an OracleSet transaction without the AssetPrice field, the following error occurs:

xrpl.models.exceptions.XRPLModelException: {'price_data_series': 'Field must have both AssetPrice and Scale if any are present'}

This behavior seems contradictory to the documented functionality. Could you please investigate and clarify the expected behavior for OracleSet transactions with missing AssetPrice fields?
