[torchiaf]

Summary

Fixes #12141

Occurred changes and/or fixed issues

Technical notes summary

harvester.vue contains a <vuedraggable> element which is not compatible with Vue3.

When navigating to the Harvester cluster's creation page, it gets an error:

and loads the Custom cluster form as fallback.

We are upgrading vuedraggable dependency and usage to be compatible with Vue3.

• Migration steps https://github.com/SortableJS/vue.draggable.next?tab=readme-ov-file#migrate-from-vue-2-version
• tag="transition-group" removed, there is known issues fixed by TypeError: Cannot set properties of null (setting '__draggable_context') SortableJS/vue.draggable.next#140 (comment)

Areas or cases that should be tested

• Harvester cluster's volumes details. Drag & drop should work properly.

Areas which could experience regressions

• Any Vue3 extension or Vue2 extension planned to be migrated to Vue3 that imports vuedraggable dep. from the shell (once a new shell version is released).
