Can you give me a text XML file where this happens? I have not found an example. If there is a test you could add, that would be great. I don't want to be needlessly defensive here.

@kddnewton no worries. It happens with this test file, with my Prettier extension for Nova.

The error message I get can be found in the issue in the first comment: stonerl/nova-prettier-extension#41 (comment)

It could also be me implementing formatWithCursor incorrect, but I only get this error with the xml-plugin. Everything else works.

I don't think you're doing it wrong, but is it possible you're using an earlier version of the plugin? I cannot get it to crash with the latest version.

I'm using the 3.4.1 that's the latest one AFAIK.

I currently apply this patch when installing all npm packages, and it circumvents the error and allows formatting XML files.

This could be something that happens only in combination with Nova. I don't mind if this patch won't go into upstream, I can keep it as part of my extension.

I think I might know what's going on here. Nova is using Apple's JavaScript Core engine.

I assume you're using node.js for testing? It could be that this is just a platform specific error.

I don't think so, if I run this in bun or safari it passes. I would be shocked if this had anything to do with the runtime as it's a logic error. Are you 100% sure you're on the latest version?

Pretty sure:

Just an update. I ran into the same error while implementing pretter-plugin-astro and prettier-plugin-sh and had to fix it the same way.

I think I will leave this as part of your extension, because I cannot figure out how to reproduce this.
