[BUG]: Service-override works inconsistently with go-redis v9

[d33kayyy]

Tracer Version(s)

2.4.1

Go Version(s)

1.25

Bug Report

I have multiple Go projects with identical setups. However, the tracing is working correctly with one project but not the other, in which the service-override cannot identify the correct dependency for a project. As a result, the time spent by downstream services is also incorrect.

I don't know if I should post it here or elsewhere, please advice.

Reproduction Code

go.mod

	github.com/DataDog/dd-trace-go/contrib/gin-gonic/gin/v2 v2.2.3
	github.com/DataDog/dd-trace-go/contrib/go-redis/redis/v2 v2.2.3
	github.com/DataDog/dd-trace-go/contrib/redis/go-redis.v9/v2 v2.2.3
	github.com/DataDog/dd-trace-go/v2 v2.4.1
	github.com/DataDog/orchestrion v1.5.0

orchestrion.tool.go

// This file was created by `orchestrion pin`, and is used to ensure the
// `go.mod` file contains the necessary entries to ensure repeatable builds when
// using `orchestrion`. It is also used to set up which integrations are enabled.

//go:build tools

//go:generate go run github.com/DataDog/orchestrion pin -generate

package tools

// Imports in this file determine which tracer integrations are enabled in
// orchestrion. New integrations can be automatically discovered by running
// `orchestrion pin` again. You can also manually add new imports here to
// enable additional integrations. When doing so, you can run `orchestrion pin`
// to make sure manually added integrations are valid (i.e, the imported package
// includes a valid `orchestrion.yml` file).
import (
	// Ensures `orchestrion` is present in `go.mod` so that builds are repeatable.
	// Do not remove.
	_ "github.com/DataDog/orchestrion" // integration

	// Just import the necessary integrations
	_ "github.com/DataDog/dd-trace-go/contrib/gin-gonic/gin/v2"     // integration
	_ "github.com/DataDog/dd-trace-go/contrib/go-redis/redis/v2"    // integration
	_ "github.com/DataDog/dd-trace-go/contrib/redis/go-redis.v9/v2" // integration
	_ "github.com/DataDog/dd-trace-go/v2/contrib/os"                // integration
	_ "github.com/DataDog/dd-trace-go/v2/ddtrace/tracer"            // integration
	_ "github.com/DataDog/dd-trace-go/v2/orchestrion"               // integration
	_ "github.com/DataDog/dd-trace-go/v2/profiler"                  // integration
)

code that create the redis client

package cache

import (

		return redis.NewClient(opt), nil
