S3 JSON Object -- json.decoder.JSONDecodeError: Extra data:

I am doing a poc to read the json files(s3 objects) in Python, but I am getting issus,

My Python code:

import json
import boto3
import os
from bson import json_util
from datetime import datetime
from kafka import KafkaProducer

print('Hello....................')

s3_resource = boto3.resource('s3')
my_bucket = s3_resource.Bucket('my_bucket')
objects = my_bucket.objects.filter(Prefix='2020/09/05/06/')

for obj in objects:
    file_content = obj.get()['Body'].read().decode('utf-8')
    json_content = json.loads(file_content)
    print(json_content)

I am getting exception:

Traceback (most recent call last):
  File "FEkafkaproducer.py", line 36, in <module>
    json_content = json.loads(file_content)
  File "/usr/lib/python3.8/json/__init__.py", line 357, in loads
    return _default_decoder.decode(s)
  File "/usr/lib/python3.8/json/decoder.py", line 340, in decode
    raise JSONDecodeError("Extra data", s, end)
json.decoder.JSONDecodeError: Extra data: line 2 column 1 (char 622)

Need your help:
