[Crash Report] In Node Graph view

[qxzcode]

Describe the Crash
Not sure exactly what happened; I was just clicking around on https://editor.graphite.rs.

Steps To Reproduce
Describe precisely how the crash occurred, step by step, starting with a new editor window.

1. Open the Graphite editor at https://editor.graphite.rs
2. ... Unfortunately I don't remember exactly what I did; I'm totally new to Graphite so I didn't really know what I was doing.
3. I was clicking around in the Node Graph, and I dragged the output of one node to create a new "Opacity" node.
4. I changed the opacity value.
5. I dragged the output of the Opacity node to one of the (output?) slots on the right (?)
6. I was clicking around those "output slots" when it crashed. It might have crashed when I clicked the "-" button on one to delete it.

Additional Details

Here's the state I ended up in:

If I hide the crash dialog with the browser devtools, here's what's underneath:

Browser and OS
Chrome 134, Unix

Stack Trace
Copied from the crash dialog in the Graphite editor:

panicked at editor/src/messages/portfolio/document/utility_types/network_interface.rs:3480:70:
removal index (is 1) should be < len (is 1)

Thanks for the report @qxzcode. It looks like it crashed whilst trying to remove the export from encapsulating_node_metadata.persistent_metadata.output_names.remove(export_index).

Given it didn't crash at the earlier network.exports.remove(export_index), the actual exports and the output names must have been out of sync for some reason. I can't really figure out why this would be the case as we always appear to modify them at the same time.

I can't seem to reproduce this issue, so it would be very useful if someone could try and get some reproduction steps.

Probably we shouldn't crash if no output name exists for the current export. A simple bounds check with a warning instead should resolve this.

Closing this since it's a year old and nobody commented about being able to reproduce it. @qxzcode, if you encounter it again, please report back with more information and we can certainly reopen it in that case.
