Index jcr:content/cq:lastReplicationAction - Not a valid JCR Name

[aemUser2345]

I am trying to create custom index on jcr:content/cq:lastReplicationAction on AEM but for some reason it complained about "Not A Valid JCR Name"

Am I missing something here?

When creating a property index in AEM, you typically only need to specify the property name itself, without the full node path. This is because property indexes focus on indexing individual property values within nodes, not the entire node structure.

Hi @aemUser2345 
It seems like you are encountering an issue with creating a custom index on jcr:content/cq:lastReplicationAction.The error message "Not a Valid JCR Name" suggests that there might be an issue with the syntax or format of the index definition
Make sure that the name attribute in the <cq:lastReplicationAction> property definition adheres to the rules for valid JCR names.

<?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:sling="http://www.apache.org/jackrabbit/sling/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0"
    jcr:primaryType="sling:OsgiConfig"
    reindex="true">

    <!-- Define the custom index -->
    <index
        jcr:primaryType="oak:QueryIndexDefinition"
        async="async"
        compatVersion="{Long}2"
        evaluatePathRestrictions="{Boolean}false"
        type="lucene">
        
        <!-- Specify the index rules -->
        <indexRules jcr:primaryType="nt:unstructured">
            <nt:base
                jcr:primaryType="nt:unstructured">
                <properties
                    jcr:primaryType="nt:unstructured">
                    <cq:lastReplicationAction
                        jcr:primaryType="nt:unstructured"
                        name="cq:lastReplicationAction"
                        type="String"/>
                </properties>
            </nt:base>
        </indexRules>
    </index>
</jcr:root>

For Property Index in OakIndexDefinition,
You need not specify path of the property, just go with all properties in propertyNames field (i.e. cq:lastReplicationAction)
And then you can specify node type for which this index is applicable in declaringNodeTypes field (i.e. cq:PageContent)
These should work.

For more info on above properties:
Checkout documentation : https://jackrabbit.apache.org/oak/docs/query/indexing.html
