ACS commons dispatcher Flush rules not working in AEMaaCS

Dear AEM Folks ,

We are currently facing one issue while configuring ACS commons dispatcher Flush rules in AEMaaCS .Our rule looks like below :

com.adobe.acs.commons.replication.dispatcher.impl.DispatcherFlushRulesImpl.cfg.json

{
  "prop.rules.resource-only":[
    "/content/dam/myproject/headless/mobile-app/message-1=/graphql/execute.json/global/testQuery",
    "/content/dam/myproject/headless/.*=/graphql/execute.json/global"
  ],
  "prop.replication-action-type":"DELETE"
}
Basically the above rule is used to flush the cache of persisted graphql query when particular Content Fragment is published.
The above configuration is placed in author server as mentioned in https://adobe-consulting-services.github.io/acs-aem-commons/features/dispatcher-flush-rules/index.html for AEMaaCS.
Now while publishing the CF , I can see in AEM author error logs as below and nothing is flushed.

ERROR :

13.09.2024 01:45:41.855 [cm-pXX8765-eXX786-aem-author-79XXX8d6f-9gqvx] *ERROR* [165.225.232.99 [1726191941847] POST /bin/replicate.json HTTP/1.1] com.adobe.acs.commons.replication.dispatcher.impl.DispatcherFlushRulesImpl Error issuing dispatcher flush rules, some downstream replication exception occurred: Replication triggered, but no agent found!

Kindly let me know what is going wrong over here as we don't have any control over replication agents in AEMaaCS.

Hi @kaushikda1 ,

Seems flush replication agent missing. 

You may refer https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/acs-commons-dispatcher-flush-rules-are-breaking-the-replication/m-p/383110

Thanks

    Hi @mukeshyadav_ ,

    But flush replication agent in AEMaaCS is taken care by Adobe itself and we don't have any control as per Onpremise.

    Thanks.

      Hi @kaushikda1 ,

      Okay,

      You may check this thread if helpful https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/flush-the-graphql-persisted-query-while-publishing-content/td-p/551615

      prop.rules.resource-only is available for AEM 6.5 only https://adobe-consulting-services.github.io/acs-aem-commons/features/dispatcher-flush-rules/index.html

       

      Thanks


      The error remains same . Tried following below config.

      {
        "prop.rules.hierarchical":[
          "/content/dam/myproject/headless/.*=/graphql/execute.json/global/*"
        ],
        "prop.replication-action-type":"INHERIT"
      }

        prop.rules.resource-only is only applicable for AEM6.5
        For AEMaaCS you probably will have to change the rules and try using 

        prop.rules.hierarchical

          Tried with 

          prop.rules.hierarchical

          but still the error remains same .
          Config :

          {
            "prop.rules.hierarchical":[
              "/content/dam/myproject/headless/.*=/graphql/execute.json/global/*"
            ],
            "prop.replication-action-type":"INHERIT"
          }

            Could you please tell me your ACS commons version which you are using ? Cloud dispatcher flush rules were introduces in ACS version 6.3, so you need to use that or some version released after that.
            Also, you need to provide absolute path to flush as per documentation, you can use regexp groups though.
            So, you will also possibly need to modify your rule to 

             

            { "prop.rules.hierarchical":[ "/content/dam/myproject/headless/.*=/graphql/execute.json/global" ], "prop.replication-action-type":"INHERIT" }

             

             But this will not be the cause for the error.
            Other possible reason could be some issue with the code deployment itself. 
            Please provide your config package via a private message to check further.

              Hi @kaushikda1 

              Can you confirm you are using cloud version of ACS commons? My guess is If you have installed non-cloud version of ACS commons, then the dispatcher flush is looking for replication agent.
