# Objective
When an item in the transparent 2d phase fails to render, bevy crashes
with _"PassSpanScope::end was never called"_ instead of outputting the
actual error to the console. This PR fixes this so that phase errors are
output to the console. It also makes bevy not crash.

## Solution
Matched the behavior of the other render phases ([like
here](9ca5540b75/crates/bevy_core_pipeline/src/core_3d/main_opaque_pass_3d_node.rs (L98-L101)))
