while printing on 1.12-rc3: `ERROR: BoundsError: attempt to access 0-element Vector{JuliaSyntax.TreeNode{TypedSyntax.TypedSyntaxData}}`

[wheeheee]

Quite easy to hit, there are other calls that I can descend into with these same arguments that also error the same way.

Thanks for the bug report. Unfortunately, the tests for the VSCode integration had been commented out, so I'm not surprised we're hitting bugs after #661. We'll want to restore them at some point, in the meantime #676 should address this particular issue.

[wheeheee]

Glad to hear that! Just to clarify, this isn't just a VSCode integrated terminal thing, I hit it on bash / Windows Terminal too.

[serenity4]

Oh, good to know, we can therefore have a test for it :)

[wheeheee]

hey @serenity4 I think you forgot to add a subdir ... when registering (and then maybe asking the registry maintainers for a manual merge)

[serenity4]

Indeed, thank you. Hopefully JuliaRegistries/RegistryCI.jl#633 (comment) applies and we don't need to perform a manual merge, but otherwise I'll ask for one in #pkg-registration on Slack.

EDIT: it doesn't apply, I asked on Slack for a merge.
