Sharepoint Rest api $batch endpoint not working for POST requests

Question

I'm trying to make a batch request using the $batch query option in sharepoint. The body of my request looks like this:

--batch_abcdefghijklmnopqrstuvwxyz
Content-Type: application/http
Content-Transfer-Encoding: binary

POST https://e.sharepoint.com/sites/J/_api/web/lists/GetByTitle('J')/items('2')/ValidateUpdateListItem HTTP/1.1
Accept: application/json;odata=nometadata

{
    "formValues": [
        {
            "FieldName": "Milestone",
            "FieldValue": "new milestone today - edit edit"
        },
    ],
    "bNewDocumentUpdate": true
}

--batch_abcdefghijklmnopqrstuvwxyz--

And I get the following error:

{"error":{"code":"-1, Microsoft.Data.OData.ODataException","message":{"lang":"en-US","value":"An invalid HTTP method 'POST' was detected for a query operation. Query operations only support the HTTP 'GET' method."}}}

Any idea why this is happening?

Hi @Tomas Gil, You could refer to following code to update list items

	var arr=[  
	{  
	   reqUrl:"https://brgrp.sharepoint.com/_api/Lists/Getbytitle('PlaceHolderList')/items(649)"  
	   ,action:"UPDATE",  
	   data:{__metadata:{type:"SP.Data.PlaceHolderListListItem"},Title:"Update Article_Using_Batch_2"}},  
	   {  
	      reqUrl:"https://brgrp.sharepoint.com/_api/Lists/Getbytitle('PlaceHolderList')/items(648)"  
	      ,action:"UPDATE",  
	      data:{__metadata:{type:"SP.Data.PlaceHolderListListItem"},Title:"Update Article_Using_Batch_1"}}  
	   ];  
	     
	BatchUtils.PostBatchAll({rootUrl:"https://brgrp.sharepoint.com",  
	batchUrls:arr}).then(r=>console.log(r));
