Problem

The schema of the root node can not be changed

Reproducer

Create new schema

curl 'https://demo.getmesh.io/api/v1/schemas' -H 'content-type: application/json' --data-binary '{"name":"new_folder","container":true,"autoPurge":false,"description":"Folder schema to create containers for other nodes.","displayField":"name","segmentField":"slug","urlFields":[],"fields":[{"name":"name","type":"string","label":"Name","required":false},{"name":"slug","type":"string","label":"Slug","required":false}]}'

assign schema to node 7d3561c9e46c41469b0060cf0d03a6cb is the uuid of the just created schema

curl 'https://demo.getmesh.io/api/v1/demo/schemas/7d3561c9e46c41469b0060cf0d03a6cb' -X POST

change schema for rootnode 3edde62224584deeaf7f4d3e68b442b8 is the uuid of the rootnode of the demo project

curl --request POST \
  --url https://demo.getmesh.io/api/v1/demo/schemas/3edde62224584deeaf7f4d3e68b442b8 \
  --header 'content-type: application/json' \
  --data '{
    "language": "en",
    "schema": {
        "name": "new_folder",
        "uuid": "7d3561c9e46c41469b0060cf0d03a6cb"
    }
}'

... http 200 response, but schema did not change

Expected behaviour and actual behaviour

schema should be changed

The schema of nodes cannot be changed currently. I'll move this issue to mesh-incubator as a feature request.
