TypeError：GetPriceVolumes 类型的 Object 不是 JSON 可序列化的 - Python

Question

尝试使用 Plotly 仪表板呈现仪表板时，我收到 TypeError: GetPriceVolumes 类型的 Object is not JSON 可序列化。 看来我需要序列化从雅虎金融API回来的jSON。 我该怎么做？ 谢谢

完整代码：

import requests
import pandas as pd
import plotly.express as px


class GetPriceVolumes:

    final_response = []
    data = {}


    def __init__(self, ticker):
        self.ticker = ticker,

    ### GET historical data for specific ticker - ie: AAPL ###
    def getSymbolData(self):

        url = "https://apidojo-yahoo-finance-v1.p.rapidapi.com/stock/v2/get-historical-data"

        querystring = {"frequency": "1d", "filter": "history", "period1": "1546448400", "period2": "1591442782",
                       "symbol": self.ticker}

        headers = {
            'x-rapidapi-host': "RRRRRRRRRRRR",
            'x-rapidapi-key': "RRRRRRRRRRRR"
        }

        response = requests.request("GET", url, headers=headers, params=querystring)
        GetPriceVolumes.final_response = response.json()

        return GetPriceVolumes.final_response

    def getConvertDataToJson(self):

        x = GetPriceVolumes.final_response['prices']



        #sample_json = jsonpickle.encode(x)
        GetPriceVolumes.data = x

        print(type(GetPriceVolumes.data))
        print(GetPriceVolumes.data)
        return GetPriceVolumes.data

    def getVolumePriceChart(self):

        df = pd.DataFrame(GetPriceVolumes.data)
        df['date'] = pd.to_datetime(df['date'], unit='s')

        fig = px.line(df, x='date', y="close")
        return fig
