Description

I went to checkout a pull request in my repository, however when I clicked on it, it failed to load.

Steps to Reproduce

These probably won't work, it's a unique situation

1. Clone an repository with one open PR and open the project in atom.
2. Open GH tab
3. Click a pull request?? Not sure.

Expected behavior:

It to view the pull request as normal.

Actual behavior:

Both the github tab and main pane turn black and do nothing until I restart Atom.

Reproduces how often:

Only on one specific pull request. It did another from the same repository perfectly fine.

This error has occurred on my home mac and my work ubuntu laptop.

yes officer this specific pull request right here is the one causing me problems

[smashwilson]

Ahh looks like we're assuming that some GraphQL node is required when it's actually nullable (... or the API changed). Thanks for the report, and also for giving us the specific pull request, that's super helpful 🙇

[annthurium]

thanks @Chewsterchew for reporting! Working on a fix.

In the mean time, a workaround is to use the "open issue or pull request" command from the command palette, which for some reason works.

[annthurium]

Just merged a fix, though it will take a bit for the fix to make its way from beta to stable.

I'm going to close, but feel free to reopen if there are additional issues or concerns.
