使用Spotipy调用Spotify API时持续出现JSONDecodeError求助

问题背景 #

刚上手Spotify的Python API库Spotipy，计划先获取歌曲ID，再通过ID提取歌曲特征。此前获取ID阶段就遇到过问题，调整后仍触发以下错误：

JSONDecodeError: Expecting value

次日执行脚本时问题暂时消失，但运行至约80%时中断。已将ID缓存至本地文件，现在尝试用缓存ID获取歌曲特征，仍触发相同错误。

复现代码 #

import pandas as pd
import api_config
import spotipy
from spotipy.oauth2 import SpotifyClientCredentials

sp = spotipy.Spotify(auth_manager=SpotifyClientCredentials(client_id=api_config.APP_CLIENT_ID, client_secret=api_config.APP_CLIENT_SECRET))        

def readChartIDs():
    
    chartIDs = pd.read_csv("../IDs.csv")
    chartIDs = chartIDs.dropna()
    
    return chartIDs

chartIDs = readChartIDs()
testSample = chartIDs.sample(10, axis=0, ignore_index=True)
testSample = testSample['IDs'].values.tolist()
song = sp.tracks(testSample)
