That will need a reproducer for us to be actionable

[tylers-epilog]

Not sure how to get reproducer either, but I'm also getting this error. Will report back if I can figure out how to reproduce it.

I noticed that the error squiggles aren't updated on save because (I think) cargo check isn't being run even though the check-on-save setting is set to true. This behavior seems related to this bug.

I noticed that the error squiggles aren't updated on save because (I think) cargo check isn't being run even though the check-on-save setting is set to true. This behavior seems related to this bug.

This isn't related, this is #18854, and it already has a fix: #18858.

[tylers-epilog]

Well that's a relief! Thanks for the heads up! Looking forward to that fix being pushed.

[hak8or]

For anyone else coming here because they saw the error in vscode when auto completion was failing, after doing a git bissect on this project between when it worked last for me via 2024-12-16 and when it stopped working via 2024-12-23, I got 02d47f3 as the commit which introduced this behavior for me.

I do see #18834 and #18888 and #18889 attempted to resolve some of the "regressions" from that commit (which was introduced via #18723).

I did try the latest release of 2025-01-13 but still saw the failing case. I also tried master which is 903bc81 as of now, but still no dice. I was hoping if I might be able to "just" revert the commit in question atop master, but the conflict resolution is above my skills with rust and familiarity with this codebase. I have been trying to get a minimal reproducible example but haven't been able to be lucky with what I extract from my proprietary codebase to reproduce this.

Hopefully this helps anyone else who might be getting hit by this.

[ChayimFriedman2]

@hak8or Do you have a reproduction?

[hak8or]

@hak8or Do you have a reproduction?

I have continued to attempt to get a minimal reproducible example since I posted a few days, but have sadly failed in my attempts. I cannot share the codebase I am seeing this in because it's proprietary. I will continue to attempt to check new releases if I see any changes, and making a small reproducible.

Would you want me to shift this to a new issue, or keep it here as is?

[ChayimFriedman2]

When you'll have a reproduction, I think a new issue should be preferred, since this one doesn't have a reproduction.

[vanviethieuanh]

Hi!
Just got similar issue with open repo I'm working on, hopefully it can help you to reproduce the issue.
The repo: vanviethieuanh/iron-spider@4dcb337
And in LSP log:

[ERROR][2025-06-10 13:32:14] ...p/_transport.lua:36	"rpc"	"rust-analyzer"	"stderr"	"2025-06-10T13:32:14.400617862+07:00 ERROR Position LineCol { line: 54, col: 20 } column exceeds line length 14, clamping it\n2025-06-10T13:32:14.400654238+07:00 ERROR Position LineCol { line: 54, col: 20 } column exceeds line length 14, clamping it\n2025-06-10T13:32:14.400659395+07:00 ERROR Position LineCol { line: 54, col: 21 } column exceeds line length 14, clamping it\n2025-06-10T13:32:14.400662604+07:00 ERROR Position LineCol { line: 54, col: 21 } column exceeds line length 14, clamping it\n"

Currently LSP Format doing nothing. Anyway to workaround?

[Yunuuuu]

Any updates for this?

[Veykril]

That will need a reproducer for us to be actionable
