# Objective
Currently, providing the wrong number of inputs to a render graph node triggers this assertion:
```
thread 'main' panicked at 'assertion failed: `(left == right)`
left: `1`,
right: `2`', /[redacted]/bevy/crates/bevy_render/src/renderer/graph_runner.rs:164:13
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
```
This does not provide the user any context.
## Solution
Add a new `RenderGraphRunnerError` variant to handle this case. The new message looks like this:
```
ERROR bevy_render::renderer: Error running render graph:
ERROR bevy_render::renderer: > node (name: 'Some("outline_pass")') has 2 input slots, but was provided 1 values
```
---
## Changelog
### Changed
`RenderGraphRunnerError` now has a new variant, `MismatchedInputCount`.
## Migration Guide
Exhaustive matches on `RenderGraphRunnerError` will need to add a branch to handle the new `MismatchedInputCount` variant.
