when calling the https://sandbox-api.bambu.life/api/autoMl/v2/prediction api i am getting 502 bad gateway error . Here is my Express app code const express = require("express"); const app = express(); const port = 3000; const axios = require("axios"); const options = { method: "POST", url: "https://sandbox-api.bambu.life/api/autoMl/v2/prediction", headers: { accept: "application/json", "content-type": "application/json", authorization: "Bearer 765f3aa5fc2c32f6de324820", }, data: { clientId: "usa_prod", model: "ensemble", customer: [ { nationality: "US", gender: "male", age: 28, race: "US", personalIncome: 8000, savingsRatio: 0.75, platformCountry: "US", customerId: "0", }, ], }, }; axios .request(options) .then(function (response) { console.log(response.data); }) .catch(function (error) { console.error(error); }); app.use(express.json()); app.get("/", (req, res) => { res.send("Hello World!"); }); app.listen(port, () => { console.log(`Example app listening at http://localhost:${port}`); }); and this is the output Example app listening at http://localhost:3000

MyAutoedit...

Hello, Is it possible to have the API "Get House Price" for houseCostCalculatorV2 to be fixed? (because I am using it for one of my school project) All the response for request of that API returns error. Sorry for the trouble. Thanks!

I tried to input the send request as var data = JSON.stringify({ "yearsToGoal": "10", "compound": "12", "confidence": "0.95", "discreteExpectedVolatility": "0.1103", "discreteExpectedReturnPerAnnum": "0.0514", "initialInvestment": "0", "annualInvestment": "1000", "currentYear": "2018", "period": "beg" }); Tried both with or without the "period" Both return this error response. {"response":{"discreteExpectedVolatility":["can't be blank"],"discreteExpectedReturnPerAnnum":["can't be blank"],"yearsToGoal":["can't be blank"],"initialInvestment":["can't be blank"],"annualInvestment":["can't be blank"],"currentYear":["can't be blank"]}} But the values worked well when it is used on the website API UI.

The web interface is not functional as it does not parse the inputs into JSON object. And secondly, the web interface does not take into consideration for null inputs. And even after I parse my object into JSON object, for instance, {'country':'Singapore', 'regionInput':null, 'cityInput':null, 'locationInput':'Ang Mo Kio', 'districtInput':'20', 'houseTypeInput':'HDB', 'roomTypeInput':'Executive'}, which is one of the returned valid datapoint. It returns me a bad request of {"error":{"statusCode":400,"name":"Error","message":"country is a required argument"}} Thirdly, if the fields are stated required, does that mean other fields in the api request itself are optional? And if so, does that mean if I input in country as Singapore and location as Ang Mo Kio, will it return all the datapoints that satisfy both conditions? Lastly, it would be nice if you save the text input of the user in the "Ask a Question" section, such that in the case that [Error: You need to fill out your name and email!], the user (me) do not have to retype everything again.

Hi, I'm unable to add the same value into an array.

What's the Risk Profile Methodology. If my bank has their own model, are we able to amend your logic?

Can you explain how does the University Calculator work?

HI, i would like to know more!
