TypeError: unhashable type: 'set' in Flask Form

I am trying to fetch data from form in Flask:
app.py
#app.route('/newProjectCreation/', methods=['GET', 'POST'])
def newProjectCreation():
try:
if request.method == 'POST':
# Data Fetch from Models Form
name = request.form['modelName']
modelDescription = request.form['modelDescription']
inputType = request.form.getlist['inputType[]']
outputType = request.form.getlist['outputType[]']
model = request.files['model']
modelLanguage = request.form['modelLanguage']
HTML
It is a simple form (not Flask-WTF form) and the fields "inputType" and "outputType" are supposed to return array as they are dynamically input fields.
Error:

I don't have prior experience in js and I am learning, if possible please simplify the response.
Thank You in advance.

Ok, I was focused on a big problem, but the problem is so simple that I did not realize it: Replace all [] with (). See below.
If you [] it assumes as dict and you are returting a list or set.
#app.route('/newProjectCreation/', methods=['GET', 'POST'])
def newProjectCreation():
try:
if request.method == 'POST':
# Data Fetch from Models Form
name = request.form('modelName')
modelDescription = request.form('modelDescription')
inputType = request.form.getlist('inputType[]')
outputType = request.form.getlist('outputType[]')
model = request.files('model')
modelLanguage = request.form('modelLanguage')

Unit tests are failing after adding environment variable to main file

I'm currently using an environment variable to hide my API's key. My unit test that is testing the API route is now failing. However, when the key was hard-coded into the main file, the tests passed. Here is my code:
import os
import requests
key = os.environ.get('key')
def test_code(state, API_BASE_URL):
url = f'https://covid-19-testing.github.io/locations/{state.lower()}/complete.json'
res = requests.get(url)
testing_data = res.json()
latsLngs = {}
for obj in testing_data:
if obj["physical_address"]:
for o in obj["physical_address"]:
addy = o["address_1"]
city = o["city"]
phone = obj["phones"][0]["number"]
location = f'{addy} {city}'
location_coordinates = requests.get(API_BASE_URL,
params={'key': key, 'location': location}).json()
lat = location_coordinates["results"][0]["locations"][0]["latLng"]["lat"]
lng = location_coordinates["results"][0]["locations"][0]["latLng"]["lng"]
latsLngs[location] = {'lat': lat, 'lng': lng, 'place': location, 'phone': phone}
return latsLngs
Here is the unit test:
from unittest import TestCase, mock
from models import db, User
from sqlalchemy.exc import InvalidRequestError
class UserViewTestCase(TestCase):
"""Test views for users."""
def setUp(self):
"""Create test client, add sample data."""
db.drop_all()
db.create_all()
self.app = create_app('testing')
self.client = self.app.test_client()
self.testuser = User.signup('test',
'dummy',
'test123',
'dummytest#test.com',
'password',
None,
"Texas",
None,
None)
self.uid = 1111
self.testuser.id = self.uid
db.session.commit()
def test_map_locations(self):
"""Does the map show testing locations?"""
with self.client as c:
resp = c.get('/location?state=California')
html = resp.get_data(as_text=True)
self.assertEqual(resp.status_code, 200)
self.assertIn('San Francisco', html)
I also think it's important to note that the application runs fine in the browser. It's just that the unit tests are not passing anymore.
UPDATE
Here is the full traceback:
ERROR: test_map_locations (test_user_views.UserViewTestCase)

I think it's most likely that your test framework is loading just the test_code() function from your test file, and not the fact that key is set up in the main body of the code. Perhaps moving your key = os.environ.get("key") into test_code() will solve your issue.

The environment variable needs to be set in the project's repository in travis CI so that all files have access to it. Here is the documentation on how to achieve this https://docs.travis-ci.com/user/environment-variables/#defining-variables-in-repository-settings

Unable to render output in flask. Exception with returning flask json.dumps on list of lists

I am having trouble in displaying output in JSON using Flask. I am calling a function that returns a list of lists which looks as:
[[["High", 0], ["Medium", 1], ["Low", 2], ["Unknown", 3]], ["test_data", [4155, 1, 25, 9.1, 2, "2.40"]], ["label", 1]]
However, in my flask application, I am unable to jsonify or json.dumps. I do like this:
def remotely_call_func(json_lol):
# print('inside remotely')
# abc =[]
# abc=ext.call_func(json_lol) # I tried to jsonify abc
# print(abc) # print the
return json.dumps(ext.call_func(json_lol)) # throws an exception
# return ext.call_func(json_lol)
#app.route('/api/v1/engine/label', methods=['POST'])
def labelJsonHandler():
if request.is_json:
# Parse the JSON into a Python dictionary
print('request is json')
content = request.get_json() # --works
app.logger.info("labelJsonHandler()..", content)
return access_data_api(content['orderId']), 200 # Return a string along with an HTTP status code
else:
return "Request was not JSON", 400
The exception that I get is:

I am able to receive the exact list of lists in my flask application. How can render this as JSON to POST using my flask?

Flask sometimes works properly and sometimes causes "builtins.IndexError" error?

If I run this code, it will be correctly paged without any error builtins.IndexError

When I look at the relevant articles, I do not understand the solution of some of them, but some do not understand it because they are not Turkish, and can you help me?
