Sling Content Distribution - unable to publish the content

[AryaBa1]

Hi Community,

I'm setting up Sling Content Distribution (SCD) in AEM as a Cloud Service to replicate content from Author to Publish using a custom agent and Java code.

Here’s the agent configuration (com.adobe.granite.distribution.core.impl.AgentConfiguration-myagent.config):

name="myagent"
enabled=B"true"
serviceName="sling/distribution/service/default"
serializationType="default"
log.level="info"
packageExporter.endpoints=["http://localhost:4503/libs/sling/distribution/services/exporters/default"]
packageImporter.endpoints=["http://localhost:4503/libs/sling/distribution/services/importers/default"]
transportSecretProvider.target="(name=default)"

And here's the code I'm using to trigger the distribution:

ResourceResolver resolver = resolverFactory.getServiceResourceResolver(
Collections.singletonMap(ResourceResolverFactory.SUBSERVICE, "distributionService"));

DistributionRequest request = new SimpleDistributionRequest(DistributionRequestType.ADD, "/content/myproject/en");

DistributionAgent agent = distributionAgent.get("myagent");
DistributionResponse response = agent.execute(request, resolver.adaptTo(Session.class));

The code runs without errors, but content is not getting pushed to Publish. Manual distribution via UI works fine.

Hi @AryaBa1,

Could you confirm your Transport Secret Provider.

Make sure you have this config on Author:

# com.adobe.granite.distribution.core.impl.AgentConfiguration-myagent.config
name="myagent"
enabled=B"true"
serviceName="myagent"
serializationType="default"
packageExporter.endpoints=["http://localhost:4503/libs/sling/distribution/services/importers/default"]
transportSecretProvider.target="(serviceName=myagent)"

And on Publish, create this OSGi config:

# com.adobe.granite.distribution.transport.impl.SecretTransportAuthenticationProviderFactory-myagent.config
serviceName="myagent"
username="distribution-user"
password="your-password"

Also worth to check:

• distribution-user exists on Publish with permissions

• The importer endpoint (default) is active

•  myagent matches in code and config

Thanks @SantoshSai it worked after adding the correct serviceName and credentials on the Publish side.

Why do you use Content Distribution to replicate content from author to publish? Isn't it possible for you to use the Replication API for that?
