Since yesterday my templ files can't be formatted by pressing: (Ctrl+Shift+I) in VS Code or VSCodium.

When the editors open the following error message pops up:

This is the output:

I reinstalled the templ extension and added this in my settings.json but nothing works. It has been working well before and I can't trace back the steps that got me to this point.

{
    "editor.formatOnSave": true,
    "[templ]": {
        "editor.defaultFormatter": "a-h.templ"
    },
}

These are some of extension settings for templ. I'm not sure what I'm supposed to do here.

Seeing the same on macOS with the latest VS Code (v1.90), Go extension (v0.41.4, gopls v0.16.0, go v1.22.3), and templ-vscode extension (v0.0.25, templ v0.2.707).

same

This has been fixed in mainline, it was a result of a change in gopls, so should be resolved in the next release. Alternatively you can install mainline now go install github.com/a-h/templ/cmd/templ@main.

[prencher]

Unfortunately changing to main now causes the issues outlined in #801.

For anybody else looking for a fix for this and running into issues after changing to main, follow along on that issue.
