Cannot create a gallery client

I am trying to create gallery client using following code:

package main
import (
	"context"
	"fmt"
	"github.com/microsoft/azure-devops-go-api/azuredevops"
	"github.com/microsoft/azure-devops-go-api/azuredevops/gallery"
)
func main() {
	organizationUrl := "https://dev.azure.com/organization" // todo: replace value with your organization url
	personalAccessToken := "pat"                            // todo: replace value with your PAT
	connection := azuredevops.NewPatConnection(organizationUrl, personalAccessToken)
	ctx := context.Background()
	galleryClient, err := gallery.NewClient(ctx, connection)
	if err != nil {
		fmt.Println(err)
	}
	extensionName := "1123"
	publisherName := "asdasd"
	galleryData, _ := galleryClient.GetExtension(ctx, gallery.GetExtensionArgs{ExtensionName: &extensionName, PublisherName: &publisherName})
	fmt.Println(galleryData.DisplayName)
}

However, I receive following error message:
API resource area Id 69d21c00-f135-441b-b5ce-3626378e0819 is not registered on https://dev.azure.com/organization.

I went through documentation and couldn't find details about this issue.

Start at the gallery.NewClient call shown in the issue and trace how it handles the API resource area error. Check the Azure DevOps organization URL and PAT assumptions against the Gallery API requirements. Done means the client can be created and GetExtension returns the requested extension without this error.
