Liquibase.rollback failing with error changelog not found

1

In my SpringBoot application, I run the following Liquibase commands:

liquibase.update(new Contexts(this.getContexts()), new LabelExpression(this.getLabelFilter()));
liquibase.rollback(1, contexts);

The update works perfectly, finding the changelog and applying the changes as expected. However, the rollback fails with the following error:

Optional[liquibase.exception.ChangeLogParseException: classpath:/changelog/changelog.yaml does not exist]

I noticed that DatabaseChangelogCommandStep.getDatabaseChangeLog uses:

ResourceAccessor resourceAccessor = Scope.getCurrentScope().getResourceAccessor();

During the update, it returns a SpringResourceAccessor, but during the rollback, it returns a ClassLoaderResourceAccessor, which seems to be causing the issue.

Any ideas on why this happens and how to resolve it?
