I believe this occurring in one of the returned changes processing functions

[nick2432]

can i work on this?

[bjester]

@nick2432 This is already assigned

[bjester]

@vkWeb I suspect is this happening when a copy change is relayed to a second editor after it's applied on the backend (this code here https://github.com/learningequality/studio/blob/unstable/contentcuration/contentcuration/frontend/shared/data/applyRemoteChanges.js#L152)

[vkWeb]

@bjester I tried that, but didn't observe any console errors. Let me re-try and will follow up on Slack.

[bjester]

@vkWeb The important aspect of the second editor is that they can't have already loaded the node that was copied. So it needs to be a node that both can access but the frontend needs to not have already loaded it into indexeddb

[vkWeb]

@bjester Got the error!

Sir what made you think like that? Like I want to know what signalled you that we need to make sure the second editor shouldn't have loaded the node to indexed DB?

[bjester]

@vkWeb Since the error was related to accessing original_source_node_id on undefined, which we do in order to copy a node, I presumed that node wasn't already loaded because in any other copying use case it must already be loaded

[vkWeb]

@bjester Okay, nice sir!
