Hmm, I am wondering what view entity is passed in if there is no such entity matching the query.

I also wonder why this should panic instead of just returning an error. The Node::run are supposed to be fallible.

the panic is thread 'main' panicked at 'view entity should exist: QueryDoesNotMatch(0v0)', crates\bevy_core_pipeline\src\main_pass_2d.rs:45:14, so panicking on the expect there. Should it return a NodeRunError in this case?

This PR makes it returns a Ok(()) which swallows the error

A similar change was made to main_pass_3d.rs in #3330, which Cart approved.

Why is there no view when the window is minimised?

Also, how come this only affects 2d?

I don't know why this happens whilst minimised. Presumably we have some code that prevents creating swapchain textures of size 0.

And as @devil-ira mentioned, #3330 added the same thing for 3d, hence that not crashing.

@DJMcNab, #4757 does the same thing for UI cameras. Can you roll in that fix and credit the author?

I can do if someone makes a pr against the branch for it 😆

I'm not in a context where I can do any manual git operations at the moment

I guess we should add a UI camera to the minimising and resizing examples too

Allow minimising in 2d (#4527)
09a3d8a 
# Objective

- We can't minimise if there's a 2d camera because ??? there legally must be a 2d target.
- Fixes #4526
- Fixes #4856

## Solution

- Make it not crash in those cases, just do nothing
- Seems to work ¯\\_(ツ)_/¯
- See also the companion commit in #3597 - 503c247
