TypeError when using link_token_create

Question

TypeError when using link_token_create

jsbrich opened this issue a year ago · comments

Using the latest release (2.3.3) of the plaid python api

@app.route('/api/create_link_token', methods=['POST'])
def create_link_token():
    user_id = time.time()
    if(request.data):
        req = request.json
        user_id = req['userId']
    if(user_id is not None):
        try:
            linkRequest = LinkTokenCreateRequest(
                products=[Products("auth"), Products("transactions")],
                client_name="JNetInc PFM",
                country_codes=[CountryCode("US")],
                language="en",
                user=LinkTokenCreateRequestUser(client_user_id=str(user_id)),
            )
            if PLAID_REDIRECT_URI!=None:
                linkRequest['redirect_uri']=PLAID_REDIRECT_URI
        # create link token
            linkResponse = client.link_token_create(linkRequest)
            pretty_print_response(linkResponse.to_dict())
            return jsonify(linkResponse.to_dict())
        except plaid.ApiException as e:
            return json.loads(e.body)
    else:
        error = [{'error': 'Invlaid User ID Provided'}]
        return jsonify(error, status=500, mimetype='application/json')

When this runs, I get

Client is opened earlier as

configuration = plaid.Configuration(
    host=host,
    api_key={
        'clientId': PLAID_CLIENT_ID,
        'secret': PLAID_SECRET,
    }
)

api_client = plaid.ApiClient(configuration)
client = plaid_api.PlaidApi(api_client)

I've tried hard-coding user_id to a string, I replaced all the code with the test_link_token_create_required() in the test methods, always the same result. Little bit of digging shows some of the values in the "headers" are None, but I can't figure out where they are set.

I see this issue has been in here a couple of times, but either no answer is given, or the answer is an incorrect input. I can't find that any of the inputs are incorrect.

Issue was .env file with PLAID client id and such was not being loaded, so values were None. I assumed the client creation function would have faulted first for that.
