a boolean value can be set to a int property successfully

[cooper-lzy]

Expected return error:
[ERROR (-1005)]: Storage Error: The data type does not meet the requirements. Use the correct type of data.

It seems that it's a feature. Boolean type value can be transformed as INT8/16/32/64. See RowWriterV2.cpp. If it's a bug, it's confusing why they use switch instead of if-else.

It is transformed indeed, think of a up cast.
