ACS commons dispatcher Flush rules not working in AEMaaCS

[kaushikda]

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.ht... for AEMaaCS.
Now while publishing the CF , I can see in AEM author error logs as below and nothing is flushed.

ERROR :

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

Hi @kaushikda ,

Seems flush replication agent missing. 

You may refer https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/acs-commons-dispatcher-flu...

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 @kaushikda ,

Okay,

You may check this thread if helpful https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/flush-the-graphql-persiste...

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.ht...

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

https://adobe-consulting-services.github.io/acs-aem-commons/features/dispatcher-flush-rules/index.ht... 

[kaushikda]

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.

@kautuk_sahni - not yet with the solution provided , hoping to get some more solutions from learned folks.

Hi @kaushikda 

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.

Hi @kaushikda 
Please check https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/dispatcher-flush-on-aemaac...

Was this resolved? I am using the latest acs-aem-commons cloud version (6.10.0-cloud) with SDK 2025.1.19352.20250131T194709Z-250100.

This is my config.

It's not working for me.

  "prop.replication-action-type":"ACTIVATE",
  "prop.rules.hierarchical":[
    "/conf/sbuxcorp/settings/graphql/persistentQueries/*=/graphql",
    "/content/dam/content-fragment/*=/grahql"
  ]
}
