Error only on publisher : LoginException: Cannot derive user name for bundle and sub service

[sindhusr]

Hi,

I have a service user who is mapped to two subservices Example:

<jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0"
    xmlns:jcr="http://www.jcp.org/jcr/1.0" jcr:primaryType="sling:OsgiConfig"
    user.mapping="[aem-demo-test.core:demoService=demo-admin]"
    />

<jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0"
    xmlns:jcr="http://www.jcp.org/jcr/1.0" jcr:primaryType="sling:OsgiConfig"
    user.mapping="[aem-test2.core:oldDemoService=demo-admin]"
    />

 This works fine in author but does not work only on publisher. It also works on publisher after I restart publisher. 

I get this error on publisher:

org.apache.sling.api.resource.LoginException: Cannot derive user name for bundle aem-demo-test.core [620] and sub service demoService.

It all works fine after I restart the bundle.

@sindhusr It may be you local AEM instance issue. Do you see this error on DEV/QA environments or developers machine also ? 

Can you once try creating new instance and verify once may not be having this issue

Hi Imran, this happens across all environments. Dev/qa and uat, prod. The solution of restart works for now but that’s not the ideal solution .

@sindhusr 

Please check if you are seeing any error while deploying code. If not, I would suggest here to raise an Adobe ticket as it is a common and we are easily replicate this issue.

This is the error I see 

"org.apache.sling.api.resource.LoginException: Cannot derive user name for bundle aem-demo-test.core [620] and sub service demoService." but I don't understand how it works on author. It also works on publisher after restart.

@sindhusr Please compare the author and publish config very closely.
