LSP crashes after being started by kakoune-lsp

[krobelus]

Describe the bug

Attempting to use templ with the kakoune editor via the kakoune-lsp plugin results in an unintelligible crash.

To Reproduce

1. Install the Kakoune binary
2. Install the kakoune-lsp binary

mkdir .config &&
mkdir .config/kak-lsp &&
echo >.config/kak-lsp/kak-lsp.toml '
[language_server.templ]
filetypes = ["templ"]
command = "templ"
roots = [".git", ".hg"]
args = ["lsp"]
' &&
HOME=$PWD kak newfile.templ -e '
set buffer filetype templ
eval %sh{kak-lsp --kakoune -s $kak_session}
set global lsp_cmd "kak-lsp -s %val{session} -vvvv --log /tmp/kakoune-lsp.log"
lsp-enable'

Expected behavior

no crash, possibly completions if I start inputting Go code

Additional context

Possible cause is that kakoune-lsp sends

To server templ: {"jsonrpc":"2.0","result":[null],"id":4}

but I don't even get a proper backtrace from templ, so I figured I report it.

[a-h]

The code action error from the logs (nil pointer) looks like a bug that was fixed in a previous version of templ - #771

The bug was triggered by a change in behaviour of gopls, so even if templ was working great, as soon as gopls was updated, it would start crashing.

I'd recommend installing the latest version, and making sure it's in your path.

[a-h]

Also, you can get templ LSP to log more by adding extra args to the 'templ lsp' command.

[krobelus]

thanks it was indeed a PATH problem, I was using an old version.
New version works fine now (now I only need to figure out why htmx-lsp won't give html tag snippet completions)

[a-h]

Great. I'm working (background task, slowly) on getting templ to support proxying down to multiple LSPs so I can improve the HTML LSP support.

Have to balance the work and life etc. 😁
