Liquibase createTable not creating primary Key

Question

I am using MySQL, using Liquibase (Liquibase Version: 4.23.1), I am generating a table in the changeset and in another changeset, I am using precondition to check if the primary key exists and then only insert the record.

        <createTable catalogName="studentdb" tableName="student">
            <column autoIncrement="true" name="student_id" type="BIGINT">
                <constraints nullable="false" primaryKeyName="pk_student_id" primaryKey="true" />
            </column>
            <column name="student_name" type="VARCHAR(20)" />
        </createTable>
    </changeSet>
    <changeSet author="adam" id="1693111591793-2">
        <preConditions>
            <primaryKeyExists tableName="student" primaryKeyName="pk_student_id" />
        </preConditions>
        <insert catalogName="studentdb" tableName="student">
            <column name="student_id" valueNumeric="1" />
            <column name="student_name" value="Mac" />
        </insert>
    </changeSet>
</databaseChangeLog>
enter code here

the command is liquibase update

The id column has constraints

<constraints nullable="false" primaryKeyName="pk_student_id" primaryKey="true" />

but still the precondition

<preConditions>
                <primaryKeyExists tableName="student" primaryKeyName="pk_student_id" />
            </preConditions>

throwing error as below

    Migration failed for changeset changelog.mysql.xml::1693111591793-2::adam:
     Reason:
          changelog.mysql.xml : Primary Key does not exist on the student
  - Caused by: Preconditions Failed

what am i missing?
