Schema Migration not working properly for all nodes

[giuseppCl]

Hello everyone,

At the moment we have the problem that some nodes cannot be updated because they do not have the latest schema version.
The nodes are of the schema ‘KnowledgeArticle’. The nodes that work correctly are on version 32.0. The nodes that do not work are still on version 28.0.

In the appendix you will find the history of the schema migration jobs as well as the schema definitions of the different versions. All jobs are in COMPLETED status.

We then tried to start a manual schema migration ({{mesh-url}}/api/v2/:project/branches/:branchUuid/migrateSchemas).
This then led to a NullPointerException, please see the attachment.

In my opinion, this is a bug in the schema migration handling.

• What can we do so that the nodes that exist in schema version 28.0 are migrated correctly to schema version 32.0?

Thank you very much.

Greetings,
Giuseppe
