    Tablestore:What do I do if the "Validate PK type fail" error message is returned when I use Tablestore SDKs?

    Last Updated:Apr 01, 2025

    If the "Validate PK type fail" error message is returned when you use Tablestore SDKs, make sure the data types of primary key columns that you specify are the same as the data types of primary key columns in the data table.

    Problem description

    The following error message is returned when I use a Tablestore SDK to write data to a data table:

    Caused by: [ErrorCode]:OTSInvalidPK, [Message]:Validate PK type fail. Input: VT_STRING, Meta: VT_BLOB. [RequestId]:00055f43-3d31-012b-62c3-980a3eefe39e, [TraceId]:02822839-3b5b-af35-409a-cf68841239fa, [HttpStatus:]400

    Possible cause

    The data types of primary key columns that you specify are different from the data types of primary key columns in the data table.

    Solution

    Make sure the data types of primary key columns that you specify are the same as the data types of primary key columns in the data table.
