Hello,

Thank you for your helpful answers. This is my first post, and I truly appreciate your support!

I’m encountering an issue while applying the Essential Meta-Model v6.20 Updates in the Essential Open Source Platform. The process fails with the following error:

Can you confirm you are trying to upgrade from 6.19 and that you have applied all the interim updates (6.16, 6.17, etc)?
Have you modified the out-of-the-box classes and slots in any way?
Have you made any meta-model extensions?

Dear Neil,

Apologies for the delayed response. I was able to update to version 6.20 after removing the annotation project (which seemed to be corrupted) and applying all previous updates as per your advice.

Thank you for your support!

Best regards,
