Issue with exporting on csv

I have created an add-on that outputs a csv file with the ratings of anki cards and the time they were rated.
In the anki-review_results folder, I stored an empty init.py, anki_rating_time_record.py, and a file named manifest.json, and after compressing it, I converted the extension to .ankiaddon.
However, I got the following error

An error occurred during the installation of anki-review-results.ankiaddon: Invalid add-on manifest.
Please report this to the add-on author in question.

Anki_rating_time_record.py is as follows
import anki_python_api
import csv
import datetime

reset anki api

Anki = anki_python_api.

review_results =

def review_did_answer_card(result, card, ease):
now = datetime.datetime.now()
review_results.append((result, card, ease, now))

register Anki API

anki.add_review_did_answer_card_callback(review_did_answer_card)

start anki

anki.run()

save the results on csv format

with open(“review_results.csv”, “w”) as f:
writer = csv.writer(f)
writer.writer([“timestamp”, “result”, “card”, “ease”])
for all_results in review_results:
writer.writer([all_result[0].strftime(“%Y-%m-%d %H:%M:%S”),all_result[1],
all_result[2],all_result[3]])

The manifest.json is as follows.
{
“id” : “anki-review-results”,
“version”: “0.1”,
“name”: “Anki Review Results”,
“description”: “Save the results of your Anki reviews in a CSV file”,
“author”: “Shohei”,
“addonType”:[“background”],
“minimumAnkiVersion”: “2.1.0”
“files”:[“Anki_rating_time_record.py”,“init.py”]
}

The version of anki in use is 2.1.58.
What can I do to make it function properly? Please let me know.

Thank you for your reply.
I re-ran the manifest.json with only name and package, but the situation did not change.
The name of the compressed folder is indeed the same as the one specified in package.
Please let me know if there is another solution.
