Could not open +page.svelte in the editor

[Loizzus]

Describe the bug

Randomly started getting this error on my Svelte projects recently when using the code inspector to open up files. Have no idea how to resolve. It only affects files with special characters in the name.

Could not open +page.svelte in the editor.

When running on Windows, file names are checked against a safe file name pattern to protect against remote code execution attacks. File names may consist only of alphanumeric characters (all languages), periods, dashes, slashes, and underscores.

launch-editor tries to protect from malicious filenames, not sure if + is a dangerous char on windoes or just too rigid check

[dominikg]

fix could take a bit as launch-editor is bundled in vite

[dominikg]

The linked change was included in vite 5.3.2

[Haukez]

and how to fix this now? I got most recent versions and still get this error.

[dominikg]

this needs a change in launch-editor first and then vite has to update the bundled version and release that.

[Loizzus]

As a temporary fix force vite to be version 5.3.1 in your package.json: "devDependencies": { "vite": "5.3.1" }, "overrides": { "@sveltejs/vite-plugin-svelte": { "vite": "5.3.1" } }

[dominikg]

please don't use partial overrides. If svelte-inspector on +page.svelte files is that important to you, go back to vite 5.3.1 entirely to ensure that you are using one consistent version.

[dominikg]

the fix for this is going to be included in the next release of vite

[Wizzel1]

Still doesn't work for me with "vite": "^5.4.0",

can you provide more info here? the fix was pretty straight forward and another windows user just reported it working with 5.4.

can you open files that do not contain a + in their name? Which windows shell and ide versions?

[Wizzel1]

Yes, I sometimes can open files that don't contain a + but it's hit and miss.

Sometimes even navigating to a component fails:

app:dev: Could not open BulkReplaceSheet.svelte in the editor.

My vscode version is 1.92.0 and I am running powershell

[dominikg]

Does your username or the project directory contain any other special characters?

[Wizzel1]

This is the path to one of my pages. Closest character to a special character is the underscore.

[dominikg]

oof, [] and () are problems tooo i guess

[oneezy]

can confirm this is still an issue with vite 5.4.2

Could not open Title.svelte in the editor.

Happening for me on Win10 as well, after update to latest version of SvelteKit 2.

Only seems to happen when inspecting elements on routes (+page.svelte), or on components not inside of routes with params. I'm guessing '+' and '[]' are not on the aforementioned safe file name pattern. Components living anywhere else seem to work fine.

[Wizzel1]

Any updates on this?

[dominikg]

latest version of launch-editor and vite should have this fixed. if you still experience files that do not open please share their full path (skip your user dir for privacy if you prefer but mention if it has any special chars)

So I am running VSCode 1.94.0 and vite 5.4.8. Maybe its the underscore in my repo name?

[Loizzus]

Can confirm, issue has not been fixed for Svelte 4.

Also the plugin does not work at all in Svelte 5.

[Loizzus]

Actually a simple test project does work. However I tested this path from an actual production project and it fails: C:\Users\loic.joachim\Documents\GitHub\nodejs-external\src\routes\portal\(orders)\ordermanagement\+page.svelte Presumably because of the -

[dominikg]

The fix is in launch-editor 2.9.1 which has been merged into vite main branch (6.0 beta) but not backported to 5.4 branch yet, sorry. still needs to wait a bit

[dominikg]

please try again with vite 5.4.9

[Wizzel1]

please try again with vite 5.4.9

Yes it works now, thanks

I still have this issue using WSL2 (Ubuntu) on Windows. Happens with every component. The file paths are fairly simple, e.g.: ~/apps/omat/my-app/src/lib/ui/img.svelte

Vite 7.1.5 and vite-plugin-svelte 6.2.0.

[dominikg]

launch-editor still does not support WSL, see https://github.com/yyx990803/launch-editor/issues/16
