回送API语法错误-JSON中的意外令牌

Question

因此，当我使用node .命令初始化API时，会出现此错误：

SyntaxError: C:\Users\Andre\FishAPI\common\models\fish.json: Unexpected token } in JSON at position 945
    at JSON.parse (<anonymous>)
    at Object.Module._extensions..json (internal/modules/cjs/loader.js:795:27)

这显然是错误所在的fish.json：

{
  "name": "Fish",
  "plural": "Fish",
  "base": "PersistedModel",
  "idInjection": false,
  "options": {
    "validateUpsert": true
  },
  "properties": {
    "_id": {
      "type": "string",
      "id": true,
      "required": true
    },
    "name": {
      "type": "string",
      "required": true
    },
    "scientific": {
      "type": "string",
      "required": true
    },
    "environment": {
      "type": "string",
      "required": true
    },
    "minClimate": {
      "type": "number"
    },
    "maxClimate": {
      "type": "number"
    },
    "minDepth": {
      "type": "number"
    },
    "maxDepth": {
      "type": "number"
    },
    "avLength": {
      "type": "number"
    },
    "maxLength": {
      "type": "number"
    },
    "maxWeight": {
      "type": "number"
    },
    "maxAge": {
      "type": "number"
    },
    "description": {
      "type": "string"
    },
    "biology": {
      "type": "string"
    }
    //** the space before the } below this line is where the error is? ** //
  },
  "validations": [],
  "relations": {},
  "acls": [],
  "methods": {}
}

因此，该错误表明上述json文件中的位置945存在语法错误。我在文件中添加了注释，以显示位置945的位置。只是}之前的空格。

这里有没有人看到我为什么收到此错误？我已多次查看文件，但似乎看不到问题。
