genai: In NewClient() c.SetGoogleClientInfo undefined (type *aiplatform.PredictionClient has no field or method SetGoogleClientInfo)

[codecrane]

Code:

https://github.com/googleapis/google-cloud-go/blame/77c1cfac704dab6704e9b55bdd8a710695dc936a/vertexai/genai/client.go#L56

func NewClient(ctx context.Context, projectID, location string, opts ...option.ClientOption) (*Client, error) {
	opts = append([]option.ClientOption{
		option.WithEndpoint(fmt.Sprintf("%s-aiplatform.googleapis.com:443", location)),
	}, opts...)
	c, err := aiplatform.NewPredictionClient(ctx, opts...)
	if err != nil {
		return nil, err
	}
	c.SetGoogleClientInfo("gccl", internal.Version)
	return &Client{
		c:         c,
		projectID: projectID,
		location:  location,
	}, nil
}

Implication:
Application does not compile as SetGoogleClientInfo() is not available in the pinned version of the Prediction client. It looks like NewClient() is attempting to call the prediction client internal c.setGoogleClientInfo()

../../go/pkg/mod/cloud.google.com/go/vertexai@v0.5.1/genai/client.go:56:4: c.SetGoogleClientInfo undefined (type *aiplatform.PredictionClient has no field or method SetGoogleClientInfo)

Solution:
Remove the call to c.SetGoogleClientInfo("gccl", internal.Version) from func NewClient(ctx context.Context, projectID, location string, opts ...option.ClientOption) (*Client, error) {

Will get a patch out but as a workaround you can pull cloud.google.com/go/aiplatform@v1.58.0, sorry about that
