Still experiencing 501 response code while batching

While batching queries to manipulate GSheets, we encounter a 501 error.

The documentation shows that it is indeed supported: https://developers.google.com/api-client-library/dotnet/guide/batch?hl=fr

Someone with python library also encountered this error: https://github.com/googleapis/google-api-python-client/issues/2085

I was curious to read that it has been encountered and fix in the past: https://github.com/googleapis/google-api-dotnet-client/issues/1634

Environment details

• Programming language: .NetCore 6
• OS: Windows
• Language runtime version:
• Package version: Google.Apis 1.57.0.0

Steps to reproduce

1. While trying to batch queries for GoogleSheet
2. the execution of each individual request works
3. Followed the documentation to batch all the request by making use of Queue()
4. Code is similar to

SheetsService curSheetsService = new SheetsService(new Google.Apis.Services.BaseClientService.Initializer()
            {
                ApplicationName = "",
                HttpClientInitializer = credentials.First(),
            });

            Google.Apis.Requests.BatchRequest batchRequests = new Google.Apis.Requests.BatchRequest(curSheetsService);

            string range = "Input - OFFER" + "!" + "A1" + ":" + "A10";

            SpreadsheetsResource.ValuesResource.ClearRequest clearRequest = curSheetsService.Spreadsheets.Values.Clear(null, "1NBTwhG7K6uTag8XC9sLM8EmbigY0mJ6KYwUd1Vh8baY", range);
            var response = await clearRequest.ExecuteAsync();         // <- this works

            batchRequests.Queue<ClearValuesResponse>(clearRequest, (content, error, index, message) =>
            {

                logger.LogInformation(error.ToString());  // <- would fail here with message 501 not implemented, not supported o
            });

            await batchRequests.ExecuteAsync();   // <- this would NOT works

1. Reponse for batch execution is

{
  "error": {
    "code": 501,
    "message": "Operation is not implemented, or supported, or enabled.",
    "errors": [
      {
        "message": "Operation is not implemented, or supported, or enabled.",
        "domain": "global",
        "reason": "notImplemented"
      }
    ],
    "status": "UNIMPLEMENTED"
  }
}

Thanks for getting back to me

It’s flag as external as this is an issue with the API and not with the .NET client library. I’m still confirming my suspicions so I can give you a good answer. I’ll update here when I know more.

Assigned to Amanda as she looked at this last time and may have insight into what’s happening.
