Cannot create origin pool

I’m starting out with Cloudflare, and I cannot manage to create a pool.

I am sending the request to https://api.cloudflare.com/client/v4/user/load_balancers/pools

with the data:

{
    'zone': 'thunderstake.io',
    'name': 'test',
    'origins': [
      {
        "name": "test",
        "address": "0.0.0.0",
        "enabled": True,
        "weight": 1,
        "header": {
          "Host": [
            "example.com"
          ]
        }
      }
    ],
    'origin_steering': {
        'policy': 'random',
    },
}

The response is

{
  "result": null,
  "success": false,
  "errors": [
    {
      "code": 1002,
      "message": "Internal error creating or modifying pool. Access Failed. Please reach out to Support.: validation failed"
    }
  ],
  "messages": []
}

Any help is appreciated!!!
