MS graph api batch response parsing

Question

   const response = await graphClient.api('/$batch').post(content);  
   const batchResponse = new BatchResponseContent(response);  

batchResponse.getResponses() is empty where as batchResponse.getResponseById() is not. any ideas whats happening here

We are invoking a batch request to fetch users like illustrated above. We do receive the response correctly but seeing issues parsing them. Please see attached sample response that we received

   {  
     "responses": [  
       {  
         "id": "0",  
         "status": 200,
