Hi,
I am trying to create an servlet which will be used to upload an asset to AEM. The whole author system is behind Microsoft OIDC authentication. So, in our case, we will be using bearer token to authenticate the servlet request.
I am trying to do a http post to the OOTB assets API.
However, the challenge here is the authentication for the OOTB assets API. If I use the bearer token in authorization header, it fails with the below error
com.adobe.granite.rest.impl.servlet.PostRequest Exception during request processing. java.lang.IllegalArgumentException: Can't create child on a synthetic root at org.apache.sling.resourceresolver.impl.ResourceResolverImpl.create(ResourceResolverImpl.java:1004) at org.apache.sling.resourceresolver.impl.ResourceResolverImpl.create(ResourceResolverImpl.java:1002) at org.apache.sling.resourceresolver.impl.ResourceResolverImpl.create(ResourceResolverImpl.java:1002) at org.apache.sling.resourceresolver.impl.ResourceResolverImpl.create(ResourceResolverImpl.java:1002) at com.adobe.granite.rest.impl.servlet.ModifyingRequest.createOrModifyResource(ModifyingRequest.java:121)
And the only way I am able to create an asset via this custom servlet is by calling the OOTB API via the direct IP with the basic admin credentials.
Is it possible to use token based authentication?

Hi @vjleo94 ,
Not sure if you have already tried using this but you will need an external application for this (nodejs)- https://experienceleague.adobe.com/en/docs/experience-manager-learn/getting-started-with-aem-headles...

Hi @anupampat ,
Thank you for the reply.
But we have custom OIDC authentication in place, and this is a OIDC access token I am talking about which is used to authorize an user in the server.
Now as a workaround, I am going to use the direct IP to access the server with basic login credentials and use the API in my servlet.
Best regards,

@vjleo94 , trust me, your approach of servlet to upload assets will 100% fail. I wrote an article explaining all challenges we faced calling servlet to upload assets - https://medium.com/@bsaravanaprakash/how-we-migrated-a-million-assets-into-aem-cloud-service-dam-ef7...
So technically you can leverage Adobe IMS to authenticate https://experienceleague.adobe.com/en/docs/experience-manager-cloud-service/content/implementing/dev...
But if you are running on AEMaaCS, servlet approach will 100% fail. Consider switching to
Do consider not writing servlets, as they are not scalable. Will easily crash AEM JVM.
