What version of Go are you using (go version)?

$ go version
go version go1.15.6 darwin/amd64

Does this issue reproduce with the latest release?

Yes.

What operating system and processor architecture are you using (go env)?

go env Output ```console $ go env go env GO111MODULE="" GOARCH="amd64" GOBIN="" GOCACHE="/Users/christianbundy/Library/Caches/go-build" GOENV="/Users/christianbundy/Library/Application Support/go/env" GOEXE="" GOFLAGS="" GOHOSTARCH="amd64" GOHOSTOS="darwin" GOINSECURE="" GOMODCACHE="/Users/christianbundy/go/pkg/mod" GONOPROXY="" GONOSUMDB="" GOOS="darwin" GOPATH="/Users/christianbundy/go" GOPRIVATE="" GOPROXY="https://proxy.golang.org,direct" GOROOT="/usr/local/Cellar/go/1.15.6/libexec" GOSUMDB="sum.golang.org" GOTMPDIR="" GOTOOLDIR="/usr/local/Cellar/go/1.15.6/libexec/pkg/tool/darwin_amd64" GCCGO="gccgo" AR="ar" CC="clang" CXX="clang++" CGO_ENABLED="1" GOMOD="" CGO_CFLAGS="-g -O2" CGO_CPPFLAGS="" CGO_CXXFLAGS="-g -O2" CGO_FFLAGS="-g -O2" CGO_LDFLAGS="-g -O2" PKG_CONFIG="pkg-config" GOGCCFLAGS="-fPIC -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fdebug-prefix-map=/var/folders/mf/bnj093qs5sl8lkpz773d0m9c0000gn/T/go-build455103357=/tmp/go-build -gno-record-gcc-switches -fno-common" ```

What did you do?

I sent a textDocument/semanticTokens/full request to gopls.

What did you expect to see?

I'd expect a response that contained semantic tokens.

What did you see instead?

{"jsonrpc":"2.0","error":{"code":0,"message":"semantictokens are disabled"},"id":2}

I've found documentation that describes settings, but when I create settings.json with the following contents it doesn't resolve the issue:

{
  "gopls": {
    "semanticTokens": true
  }
}

Here are the exact commands that I'm sending:

Ha! I spelled "initializationOptions" wrong. 🤦

Just got a response:

{"jsonrpc":"2.0","result":{"resultId":"2020-12-23 12:17:10.435932 -0800 PST m=+40.572894509","data":[0,0,7,0,0,0,8,4,0,0,1,0,6,0,0,0,8,3,0,0,1,0,4,0,0,0,5,4,0,0,1,4,3,0,0,0,4,7,0,0,0,8,13,0,0]},"id":2}

Admittedly that data structure isn't what I was expecting, but I'm sure it's documented somewhere. Sorry for the noise!
