How to fix error code `DuplicateTargetEntries`?

Question

I am trying to integrate my own app with the user provisioning features of AzureAD,
and having trouble with the error DuplicateTargetEntries when provisioning Groups.

I understand that the error is due to the duplication occurring.
However, since I was asked for the same resource twice, I only responded to the same resource twice, so it is not considered a duplicate.

The requests and responses that are treated as DuplicateTargetEntries are below.

Request from AzureAD

   GET /Groups/8c60f8b2-d90b-422c-83df-ff1ec8070de7?excludedAttributes=members  

Response from MyApp

   {  
       "display": "test-group",  
       "id": "8c60f8b2-d90b-422c-83df-ff1ec8070de7",  
       "meta": {  
           "resourceType": "Group",  
           "location": "Groups/8c60f8b2-d90b-422c-83df-ff1ec8070de7"  
       },  
       "schemas": [  
           "urn:ietf:params:scim:schemas:core:2.0:Group"  
       ]  
   }  

Request from AzureAD

   GET /Groups?excludedAttributes=members&filter=displayName+eq+%22test-group%22  

Response from MyApp

   {  
       "Resources": [  
           {  
               "displayName": "test-group",  
               "id": "8c60f8b2-d90b-422c-83df-ff1ec8070de7",  
               "meta": {  
                   "resourceType": "Group",  
                   "created": "2020-11-24T02:05:42Z",  
                   "lastModified": "2020-11-24T02:05:42Z",  
                   "location": "Groups/8c60f8b2-d90b-422c-83df-ff1ec8070de7"  
               },  
               "schemas": [  
                   "urn:ietf:params:scim:schemas:core:2.0:Group"  
               ]  
           }  
       ],  
       "itemsPerPage": 100,  
       "schemas": [  
           "urn:ietf:params:scim:api:messages:2.0:ListResponse"  
       ],  
       "startIndex": 1,  
       "totalResults": 1  
   }  

Result of provisioning logs

   Duplicate entries exist in the target. Exactly one entry was expected, but the number found was 2. Those entries matched on these identifiers: 8c60f8b2-d90b-422c-83df-ff1ec8070de7 8c60f8b2-d90b-422c-83df-ff1ec8070de7.  

I don't understand why these response results as DuplicateTargetEntries.

Of course, I've already checked some documents.

Any advice would be appreciated.
