We are using the WebApi for creating different objects. Creating new nodes or containers works without problems, but the API returns an error when creating a new zone. We are sending this JSON:

{
    objectType: 6
    name: "NewZone"
    parentId: 1
}We are setting parentId = 1, because the object "Entire Network" has object id 1. This returns an "Internal error" with code 46.

I did take a look at the code and it seems impossible to create a node with parentId = 1.

Can you check this?

Created https://track.radensolutions.com/issue/NX-2596 for this

Just fixed it. Official fix will be in 5.1, but if you need it to work in 5.0, you can rebuild web API from source branch stable-5.0 - fix is backported here as well.

Best regards,
Victor
