Upload Capture Model

[hawkenbury]

Hi,

I am new to Madoc and am experimenting with it.
I have installed the docker instance and linked a few items (IIIF images and collections) on my test instance. This all seems to work well.
I am now looking at annotating them so have tried to upload the following capture model - which was generated using the tool in the documentation, it is about as simple as it could be, it is just a single tag;

{
"id": "0b7a0b04-1caf-4cac-8cf2-0c448d503f2f",
"type": "entity",
"label": "Root",
"properties": {
"tag": [
{
"id": "916dfc69-4f33-4afb-8af4-361f5fa87ad2",
"type": "text-field",
"label": "Tag",
"value": "",
"allowMultiple": true,
"pluralLabel": "Tags",
"revision": "daba7d42-c95f-4725-b0c7-c11705e9af86"
}
]
},
"revision": "daba7d42-c95f-4725-b0c7-c11705e9af86"
}

When I use Madoc to upload this I get the following error;

Am I doing something wrong?
Any help appreciated.
