detailed problem description

I am attempting to create an endpoint that uses the newer gitlab go-client.

The legacy client (https://github.com/xanzy/go-gitlab) has been archived as read-only, and while still viable, active development has moved to https://gitlab.com/gitlab-org/api/client-go.

When I add "gitlab.com/gitlab-org/api/client-go" to the imports in services/gitlab/gitlab.go, encore is changing the go.mod file from go 1.23.0 to go 1.23.4. Seems logical, as that Go version is what the new Gitlab client is requiring. However when I attempt to run the project (which is doing a simple "get user" endpoint as a smoke test), the encore run fails with:

'go mod tidy' failed: go: /Users/<MY_USER>/Library/Caches/encore-build/encore-demo-zazi/build/go.mod requires go >= 1.23.4
(running go 1.23.0; GOTOOLCHAIN=local)

I get this message even though:

1. my local go version is 1.23.4
2. my GOTOOLCHAIN is set to "auto"

WorkAround

Work around is to persist with the legacy Github client, but I'd like to be make the new Gitlab client work.

What I've tried

• validated Go version and encore versions
• uninstalled and reinstalled Go
• cleared encore build cache
• uninstalled and reinstalled Encore
• setting go.mod to go 1.23.0 does not allow the Gitlab client to build
