Validating json fails when key = "type"

[m3s5ts]

I'm using jsonvalidator v2.0.0 with RF v4.1.3 and Python v3.10

Whenever I have a json that contains the key "type", the validator returns "Failed validating 'type'

Below are two jsons where the only difference is the second key:

Works
Schema: { "id": "integer", "custom": "string" }
Body: { "id": 1024, "custom": "TEST" }

Doesn't work
Schema: { "id": "integer", "type": "string" }
Body: { "id": 1024, "type": "TEST" }
