FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory

[Suniron]

On Windows 11 / WSL2 i got many crashes of Volar and error is about JavaScript heap out of memory

Please, not that I'm using vscode insiders but the rest of my team have the same problem and are on vscode classic.

I downgraded my typescript version from 5.2.2 to 5.1.3 since i have seen in the Volar changelog that it was supported a few versions ago.

When I haven't the error, the save code action is really long, and typing is not always refreshed in Vue files.

I installed Vue Langage Features (Volar) v1.8.11 (the problem is also present with 1.8.1 or 1.8.10 for example) and using it in take overmode, vue-tsc 1.8.11 .

I'm working on a monorepo with multiple apps and packages.

Please, see the full error bellow (i activated trace server: messages):

[Trace - 2:24:08 PM] Sending request 'textDocument/inlayHint - (711)'.

I hope anyone can help us! 🙏 It's really hard to work with Volar in this state.

Bump? 😕 This has become a constant blocker for our GitHub workflows

Check all your tsconfig files 👍

id love to know what im looking for in these ts files youre telling me to check. all of our ts files are properly configured and have not changed in the past month and im now running into this issue after upgrading to win 11.

I'm on a fresh install and currently am getting this behavior after 2 days of it working correctly (which was great while it lasted). the fact that it started being unable to function after a few days tell me that theres probably some missing clean up

I just ran into this issue in Github workflows as well. Any option to have this looked at?

[davidmatter]

Is this one still an issue in the latest 2.x?

[romansp]

If someone else stumbles upon this issue.

We started seeing this quite randomly and only in our type-check runs during CI builds. No configuration changes or package upgrades, only merged a new feature with about 20-25 of new .vue files. Hard to pin-point what's the root cause to create a minimal repro.

We were on v2.0.29 of vue-tsc. Switching to https://github.com/vuejs/language-tools/pull/4714 via pkg.pr.new seems to help us for now.
