Drive API v2 (1.16) File Watch requests being denied when using Batch Request

Hi,

I’m getting 403 watchDenied errors when I try to make File Watch requests in a Batch Request. Sending them normally is fine. I’m presuming that batching of File Watch requests is permitted?

Additional info: If I set an incorrect Address, I get the usually unpermitted webhook address error, so it doesn’t feel like the request I’m making is incorrect.

Example code:

var request = new BatchRequest(service);
request.Queue<Channel>(service.Files.Watch(
    new Channel
    {
        Id = [Guid being used],
        Type = "web_hook",
        Address = [notification endpoint],
        Token = [token being used],
        Expiration = DateTime.Now.AddHours(1).ToUnixTimeMilliseconds()
    }, fileId)
    , (content, error, i, message) =>
    {

    }
);
await request.ExecuteAsync();

If I send a normal request such as the below, then all is OK.

Channel channel = new Channel()
{
    Id = [Guid being used],
    Type = "web_hook",
    Address = [notification endpoint],
    Token = [token being used],
    Expiration = DateTime.Now.AddHours(1).ToUnixTimeMilliseconds()
};
service.Files.Watch(channel, fileId).Execute();

Had an update from the developer support team.

Unfortunately watch requests are known to largely incompatible with Drive batch requests. Our Drive team recommended to make watch requests separate from other requests.
