TagManager v2 batch requests return 404

Hello. I was trying to send batch request to TagManager API and got 404 error. Here is my code:

var service = new TagManagerService(new BaseClientService.Initializer()
{
    HttpClientInitializer = credential, ApplicationName = "..."
});
var batchRequest = new BatchRequest(service);
foreach (var variable in toAdd)
{
    batchRequest.Queue<AccountsResource.ContainersResource.WorkspacesResource.VariablesResource.CreateRequest>(
        service.Accounts.Containers.Workspaces.Variables.Create(variable, workspace.Path),
        (content, error, index, message) =>
        {
           // ...
        });
}
await batchRequest.ExecuteAsync(cancellationToken);

It fails with HttpRequestException:

System.Net.Http.HttpRequestException: Response status code does not indicate success: 404 (Not Found).
   at System.Net.Http.HttpResponseMessage.EnsureSuccessStatusCode()
   at Google.Apis.Requests.BatchRequest.ExecuteAsync(CancellationToken cancellationToken)

I’ve seen this announcement - https://developers.googleblog.com/2018/03/discontinuing-support-for-json-rpc-and.html and i send homogenous request to specific api. But it still doesn’t work.

Request goes to https://www.googleapis.com/batch/tagmanager/v2 and if i open it browser it also shows 404 page. I’ve checked discovery document - https://www.googleapis.com/discovery/v1/apis/tagmanager/v2/rest - and there is same batch url

"batchPath": "batch/tagmanager/v2"

However, if i initialize batch request with old global batch url value, e.g

var batchRequest = new BatchRequest(service, "https://www.googleapis.com/batch");

it works. But soon this url will be switched off, so this is not a solution.

I’m not sure this is a client library problem, but i hope someone can help me here =) Thx.

As an FYI, this is being fixed. It might take a few days before the fix is in and rolled out, but I’ll update here when it’s done. Again, thanks for reporting!
