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

    Last Updated:Apr 01, 2025

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

    Problem description

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

    Caused by: [ErrorCode]:OTSInvalidPK, [Message]:Validate PK size fail

    Possible cause

    The number of primary key columns that you specify is different from the number of primary key columns in the data table.

    Solution

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