json.decoder.JSONDecodeError:尝试解析JSON字符串时出现无效控制字符错误。

import json
import pprint

json_data = None
with open("C:\\Users\\75\\OneDrive\\PROJECT P1\\Work_1.0\\CBP\\server.txt", 'r') as f:
    data = f.read()
    json_data = json.loads(data)

pprint.pprint(json_data)
f.close()
jsonString = json.dumps(json_data,default = str)
jsonFile = open("converted.json", "w")
jsonFile.write(jsonString)
jsonFile.close()

要求是从文本文件导入未格式化的转储数据，并转换为JSON，然后使用python将其写入.json文件
获取以下错误
