Describe the bug

The VS Code Go extension is encountering an issue with the Golang language server connection, resulting in the following error messages:

[Info  - 21:55:32] true

@vishaljangid1729 Thanks for the report. The message in the log seems suspicious:

[Info - 21:55:32]
true

Can you add the following to the setting and share the logs from both "gopls" and "gopls (server)" channels?

    "go.trace.server": "compact",
    "go.languageServerFlags": [
        "-rpc.trace",
     ],     

There will be a squiggle under "compact", but it's ok.

And, finally, can you try a clean install of the gopls using the "Go: Install/Update Tools" command or go install golang.org/x/tools/gopls@latest and see how it goes?

[vishaljangid1729]

@hyangah Thanks for your update. Despite applying the recommended changes and reinstalling gopls, the issue persists. Below are the logs from both gopls and gopls (server) channels:

To ensure it's not the same issue as https://github.com/golang/go/issues/63997

Can you share the following output?

$ /usr/bin/clang --version
$ which clang

and also see if manual codesigning addresses the issue:

$ codesign -f -s - <path_to_your_gopls>

[vishaljangid1729]

$ /usr/bin/clang --version

Apple clang version 15.0.0 (clang-1500.0.40.1)
Target: arm64-apple-darwin23.1.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

$ which clang

/opt/homebrew/opt/llvm/bin/clang

[vishaljangid1729]

@hyangah Thanks After applying the manual code signing, the issue has been resolved, and gopls is now functioning as expected.

Hey @hyangah @vishaljangid1729

I tried the manual code signing route, but I still have the same issue

I get the update message each time, and I try to update but I still get the same popup everytime. Also the version of gopls is 0.14.2 which I think is the latest stable version.
