Stored procedure - dbType:System.Date - Always Encrypted bug

We are using SQL Server 2016 with Always Encrypted for a few columns. One of the column types is date . When trying to execute a stored procedure, we get the following error. Switching the column to Datetime (or Datetime2) works. Using ADO instead of Dapper works fine with the column type of date

//Add the paramter
parameters.Add("@DATE_OF_BIRTH",dob,dbType:DbType.Date);

Actual Error

"Message": "No mapping exists from object type System.Date to a known managed provider native type.",
