lsp error when ı reload or open templ file #800

Closed BeratHundurel closed 1 week ago

BeratHundurel commented 1 week ago

I am getting an error in VS Code that says 'connection to server got closed' when I reload the page or open new templ file. I logged the error and found this error message: 'unable to complete because the sourcemap for the URI doesn't exist in the cache.'

I will attach the log file. Also, in the command line, I am able to execute commands like "templ lsp --help", and "which go gopls templ" command give me correct results. templ.log

I'm facing the same issue. Any idea how to fix it? This is what I have go version go1.22.2 darwin/arm64

I'm affected too. go version go1.22.1 darwin/amd64 VS Code reports:

gopls.log templ.log

DarioDT75 commented 1 week ago

Update: in a machine that was working fine, it started to happen once gopls was updated to 0.16.0

Yeap. Rolled back to gopls@v0.15.3 and that fixed the problem. Thnx.

joerdav commented 1 week ago

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

advdv commented 1 week ago

@a-h @joerdav sorry for pinging but I think it might be worth it to roll a new release just to fix this because changing to the mainline release "@main" triggers this issue: https://github.com/a-h/templ/issues/801. Or maybe create a pinned issue to advise users to prevent new issues from being created for the same problem, e.g:

For others, I think the best way currently is to downgrade gopls to 0.15.3:

Thank you @advdv, just chiming in to say I'm getting the exact same issue and I was wondering how to fix it :-)

a-h commented 1 week ago

Fixed in https://github.com/a-h/templ/releases/tag/v0.2.731
