My Setup: - go: go version go1.24.4 linux/amd64 - gopls: golang.org/x/tools/gopls v0.19.1 - code: 1.101.1 - vscode-go extension: 0.46.1

The Problem: When I type arguments into a function, the "parameter hints"-box highlights the current parameter in blue. This doesn't work with gopls v0.19 anymore.

I tested with the pre-release v0.47.3 of this extension, but the issue still persists :(

I thought I was going crazy. I tried multiple versions of this extension, and all of them had the same problem.

Thanks for reporting this, I'm also able to reproduce and have a fix working locally. I think there might have been a change in how VSCode uses the SignatureInformation.activeParameter field that caused this to break

Change https://go.dev/cl/683975 mentions this issue: gopls/internal/protocol: fix SignatureInformation.activeParameter omitempty
