Can't create child on a synthetic root

[shaheenas113483]

I have recently upgrade my AEM instance from 6.3 to 6.5 and when I try to do Roll Out as admin, I get the Error: Can't create child on a synthetic root.

What does this error imply?

[kautuk_sahni]

Can you just check this with admin user or add everyone group to root folder(I do read that you having given full access)?

If this problem still persists then create a case with Support with Referring  CQ-4218938.

I have seen this exception in a few other use cases like folder creation, user creation etc. Can you provide the complete error message?

Is this happening only on Rollout process?

[shaheenas113483]

Earlier it was happening only during roll out, now its happening for anything that I do, which requires node creation. Error:

Check out this post Getting error "Can't create child on a synthetic root" in 6.3  and try kautuksahni​'s suggestion.

Hi,

Did u find any solution. I am also facing similar issue while installing package in aem 6.5

[shaheenas113483]

Hi Srikanth,

The issue was due to missing permissions at the node level. You can add permissions to the required node from the Access Control Tab. Suppose I needed to add permissions to root level and also some specific permissions to var node. In my case I needed to add system users to those node and give the users permissions.

Regards,

Shaheena

[OliverSapient]

Which users you added?

what permissions were give. I have exact same issue.
