All Form break when array of documents used in 'documents preview' in 8.7

[Szik]

Describe the bug

All Form (created and new forms) remain without elements in 'documents preview' in 8.7.
Likely this bug is present in 8.8 but was not tested yet.

Steps to reproduce

1. create Form with 'document preview'
2. under 'General' enter an array (such as '[doc]') in 'Document reference'
3. reloading any Form will lead to no form elements being shown

Expected behavior

forms keep their normal function when entering using an array of documents.

Environment

• OS: Linux
• Camunda Modeler Version: 8.7.0-alpha4
• Execution Platform: Camunda 8

CC @camunda/hto-frontend, can you have a look?

[gbetances089]

@camunda/hto-frontend did you have the time to look at this? is a bit urgent/release blocking here

@gbetances089 No, because it wasn't mentioned it was a release blocker
Next time for form related things ping us on #ask-human-task-orchestration-team in Slack so it's faster

I'll take a look now

Ahh, gotcha, will bring this to the QA team too for awareness

I have a fix for it, I'm waiting for a review and clarification how to backport this to the web modeler

@nikku We will have to backport it to the desktop modeler, this happens there too

Backport or forward fix? Should be sufficient to release with v5.33 (the next Modeler release).

Backport or forward fix?

We're not sure yet. On one side this is quite a major bug since a user would not be able to open even a valid form after this bug happens on the other side the document preview has not been officially released yet. I'm syncing with @wollefitz on this Slack thread in case you want to join

document preview has not been officially released yet.

For Desktop Modeler this means forward fix. Let's aim to have it fully working with the next release. Great to see that we find these bugs now (rather than later).

Since the document preview is not available in the current stable release, I'd rather not push for an early patch of the Desktop Modeler. As an alpha feature, it is expected to break.

Just writing what I wrote on the release thread on Slack

We decided that since the document preview component hasn't been officially released yet we don't consider it a release blocker for SM we will merge the fix on Web Modeler main to make the fix available ASAP in SaaS but for the SM versions this will only be available on the next release
