Issue mocking(moq) ExecuteAsync for unit test(xunit)

a moq of ExecuteAsync in my unit testing is throwingInnerException = {"Async operations require use of a DbConnection or an IDbConnection where .CreateCommand() returns a DbCommand"}. Execute seems to work fine.

private  void SetupExecuteAsync ()
        {
            var dataParameterCollection = new Mock<IDataParameterCollection>();
            dbCommandMock.Setup(x => x.Parameters).Returns(dataParameterCollection.Object);
            dbCommandMock.Setup(x => x.ExecuteNonQuery()).Returns(It.IsAny<int>());
            dbConnectionMock.Setup(s => s.CreateCommand()).Returns(dbCommandMock.Object);
        }

I am mocking DbCommand object and Execute and ExecuteAsync seem to have the same parameters so I'm not sure why I am getting this error.

return connection.Execute(sql, dbParams, commandType: commandType);
 vs
return await connection.ExecuteAsync(sql, dbParams, commandType: commandType).ConfigureAwait(false);

Begin at Dapper's ExecuteAsync entry point and compare it with Execute, then trace the connection's CreateCommand path and the DbCommand setup shown in SetupExecuteAsync. Reproduce the xunit/Moq failure and verify that the async call completes without the reported DbConnection/DbCommand exception.
