Content Loss in RichText Fields After Upgrading to Umbraco 15.2.0

[martinthogersen]

Which Umbraco version are you using? (Please write the exact version, example: 10.1.0)

15.2.0

Bug summary

When upgrading an Umbraco website from version 13.6.0 to 15.2.0, some content is lost.

The issue affects RichText Data Types nested within BlockList Data Types.

In the image below, the left side shows Umbraco 13.6.0, while the right side displays 15.2.0, highlighting the missing content.

During the upgrade, the following error appears in the console:

System.Text.Json.JsonException: JSON deserialization for type 'Umbraco.Cms.Core.RichTextEditorValue' was missing required properties including: 'blocks'.

Hi there @martinthogersen!

Firstly, a big thank you for raising this issue. Every piece of feedback we receive helps us to make Umbraco better.

We really appreciate your patience while we wait for our team to have a look at this but we wanted to let you know that we see this and share with you the plan for what comes next.

• We'll assess whether this issue relates to something that has already been fixed in a later version of the release that it has been raised for.
• If it's a bug, is it related to a release that we are actively supporting or is it related to a release that's in the end-of-life or security-only phase?
• We'll replicate the issue to ensure that the problem is as described.
• We'll decide whether the behavior is an issue or if the behavior is intended.

We wish we could work with everyone directly and assess your issue immediately but we're in the fortunate position of having lots of contributions to work with and only a few humans who are able to do it. We are making progress though and in the meantime, we will keep you in the loop and let you know when we have any questions.

Thanks, from your friendly Umbraco GitHub bot 🤖 🙂

Hello, this is sadly a regression, we are aware and are looking to fix it ASAP 🕵
Look out for a patch coming hopefully tomorrow 😁

I wIll go ahead and close this, as it is already reported here #18252

Thanks for reporting though! 🐛

@Zeegaan Thank you. Where can I follow the updates? You're linking to this issue 😅

[Zeegaan]

Sorry about that... Fixed the link in the comment now 🙈

[martinthogersen]

@Zeegaan This issue is still present in version 15.2.1. Unfortunately, content is still lost during migration, and the same error described above occurs.

I believe this is a critical bug that needs to be investigated and resolved. I've encountered it on two Umbraco websites we are in the process of upgrading.

@martinthogersen Feel free to re-open this, if you can still reproduce in 15.2.1 🚀

@Zeegaan I don't have permission to reopen:

Having a look at this. If you have a small example database I can get started with, please send it my way.

[martinthogersen]

@Migaroez Please share info about where to send the database copy to you.

Same as last time ;)
