Liquibase error After migrating from spring boot 2.2.7 to 3.2.4

I recently migrated my project from Spring Boot 2.2.7 to 3.2.4 and started encountering several Liquibase errors Caused by: liquibase.exception.LiquibaseException: Error parsing db/changelog/RC-101/002_create_entitlement_user_table.yml : Error parsing db/changelog/RC-101/002_create_entitlement_user_table.yml: Unknown change type 'changeSet'. Check for spelling or capitalization errors and missing extensions such as liquibase-commercial.

My change set is

This change set was working fine in Spring Boot 2.2.7. Is this issue related to Liquibase or due to the Hibernate version upgrade? Is there any changelog documentation that I can refer to for resolving this issue?

Additional Information:

Spring Boot version: 3.2.4 Liquibase version: 4.24.0 Hibernate ORM version: 6.4.4.FINAL Hibernate Validator version: 8.0.1.FINAL Any help or pointers would be greatly appreciated!

Not sure how or why that changelog worked before because all changesets after id=2:author=Jhon Doe are nested below it. That's an invalid configuration since indention/whitespace are meaningful in YAML. Liquibase probably fixed the YAML parser to better adhere to those conventions. Try this changelog:
