BubbleGo Keeps Crashing - Nested data structure

[oliviercoolen]

Hi everyone,

Our mobile app (BubbleGo, not yet deployed) keeps crashing whenever we try to load a nested data structure. I’m on an iPhone 16 (18.5)

Here’s how our database is set up with relational links (each child references its parent, no lists on the parent itself):

• Plannings → each Planning has a list of Locations

• Locations → each Location has a list of Assignments

In the app, we’re displaying this using a ShortList nested inside another ShortList, which is then nested inside a Vertical List.

Example with dummy data:

I’ve already filed a bug report, but I’m wondering, has anyone else run into this issue with a similar database structure? If so, how did you solve it (I prefer using Bubble’s native editor, not a wrapper)?

For those with a similar issue → using lists on your data type instead of having a ChildToParent reference fixes this. Probably because we now only need one query, instead of multiple.

@oliviercoolen ah so is it the extra do a search for that seems to be causing the crash?

[oliviercoolen]

@nick.carroll That’s what I thought. But unfortunately, I’m experiencing this blank page again.

Hey @oliviercoolen , any chance you found a solution yet?

I’m facing a similar issue in two different views: one that I just developed and also one that was already working a couple months ago (tested a lot on TestFlight), but started crashing now.

The one that I just developed loads initially, but then crashes with some actions. The one that already worked doesn’t even open now.

My data schema is a bit different. I have a Workout type with a list of Exercise Details, but them these exercises have two numeric variables: order and sub-order.

With that I have a Short List of number/index, for each item I filter the exercises by order. Them the second Short List is of type Exercise Detail and it shows the exercises ordered by sub-order.

So that means that in my case I don’t have nested database searches. All data is result of filters on the Workout that is a property of this view.

One more detail: the issue never happens on view load. It only crashes when I change the database. The two arrow buttons changes the order of the exercises inside the list. The trash button deletes all Exercise Details within its card and fix the order of the remaining ones. The workflows themselves works, I checked the logs and the expected result and everything is fine. But the app crashes with a white screen after the action.
