Square-Connect 400错误-哪些字符无效？

Question

我收到了一个400，看起来是有效的json (通过JSONLint验证)。Square connect不喜欢description字段：

{
"requests": [
    {
        "method": "POST",
        "relative_path": "/v1/me/items",
        "access_token": "xxx-xxxxxxxxxxxxxxxxxx",
        "body": {
            "name": "9001 Donald Duck",
            "description": "’a’",
            "abbreviation": "test",
            "visibility": "PRIVATE",
            "available_online": false,
            "variations": [
                {
                    "name": "credit card payment",
                    "pricing_type": "FIXED_PRICING",
                    "price_money": {
                        "currency_code": "USD",
                        "amount": "-8735"
                    },
                    "sku": "7fa314q7_B9001_0",
                    "track_inventory": true
                }
            ]
        }
    }
]

}

同样的问题也会发生在这些字符上：“ ”

当我尝试在仪表板上键入这些字符时，我得到“很抱歉，但出了点问题”。因此，显然应该避免使用这些字符。

是否有无效字符的列表？此外，如果您回发了导致失败的json对象部分，也会很有帮助。浪费时间试图找出原因似乎是愚蠢的，因为它在Square的一端是已知的，不是吗？

我有时会收到400，too.request是续订的，参数在下面。

  def refresh_access_token!
    ....
    begin
      #renew api
      response = oauth_connection.post SQUARE_RENEW_URL do |req|
        req.headers['Authorization'] = "Client #{SQUARE_CLIENT_SECRET}"
        req.headers['Content-Type'] = 'application/json'
        req_body = req.body = "{ \"access_token\": \"xxxxx-xxxxxxxxxxx\" }"
      end
    ....
  end

  def oauth_connection
    @oauth_connection ||= Faraday.new(SQUARE_CONNECT_URL) do |conn|
      conn.request :url_encoded
      conn.request :json
      conn.response :json, :content_type => /\bjson$/
      conn.adapter Faraday.default_adapter
    end
  end
