[SOLVED] Moralis SDK Error while creating Stream

Moralis General
#1

Hey guys,

I’m trying to create a stream using NGROK and I’m getting the following error:
MoralisError [Moralis SDK Core Error]: [C0006] Request failed, Bad Request(400): Could not POST to http://2405-201-a-edf6-2097-252.ngrok.io/webhooks/test. Please check your webhook URL.

This is the post route I have set up in my main index.js file:

app.post("/webhooks/test", (req, res) => {
  console.log(req.body) // Call your action on the request here
  res.status(200).end() // Responding is important
})

Any idea why this isn’t working?

Is that URL reachable with a regular POST request? You can try with a client like cURL or Postman.

Also you can return something like a message in this route handler just so it’s clearer.

#3

I added a message but I’m not getting it. However I think I am getting some info from moralis. Here is a pic of my ngrok status page.

This is my addStream code:

const Moralis = require("moralis").default
const {EvmChain} = require("@moralisweb3/evm-utils")
// const { headers, body } = request;


async function main() {

    Moralis.start({
    apiKey: 'config.MORALIS_API_KEY',
    });


    const whoopyCreatedAbi = [{
        anonymous: false,
        inputs: [
            {
            indexed: true,
            internalType: "address",
            name: "instance",
            type: "address"
            },
            {
            indexed: true,
            internalType: "address",
            name: "creator",
            type: "address"
            }
        ],
        name: "NewClone",
        type: "event"
    }]

    const options = {  
        chains: [EvmChain.MUMBAI], // Ethereum Name Service so we only monitor Ethereum  
        description: "Created Whoopys", // your description  
        tag: "whoopyCreated", // give it a tag  
        abi: whoopyCreatedAbi,  
        topic0: ["NewClone(address,address)"],  
        includeContractLogs: true,  
        webhookUrl: "http://EDITEDOUT-.in.ngrok.io/webhook", // webhook url to receive events,  
    };

    const stream = await Moralis.Streams.add(options)

    await Moralis.Streams.addAddress({
        id: stream.id,
        address: "0x24290447ee215bb2565F53e1c6092BA8b1fhr75y"
    })
}

main() 
    .then(() => process.exit(0))
    .catch((error) => {
        console.error(error)
        process.exit(1)
    })

The is my index.js:

import Moralis from 'moralis';
import express from 'express';
import cors from 'cors';
import config from './config';
import { parseServer } from './parseServer';
// @ts-ignore
import ParseServer from 'parse-server';
import http from 'http';
import verifySignature from './helpers/utils'

export const app = express();

Moralis.start({
  apiKey: config.MORALIS_API_KEY,
});

app.use(express.urlencoded({ extended: true }));
app.use(express.json());

app.use(cors());

app.use(`/server`, parseServer);

app.post("/webhook", (req, res) => {
  console.log(req.body) // Call your action on the request here
  console.log("Handled!")
  res.status(200).end() // Responding is important
})

const httpServer = http.createServer(app);
httpServer.listen(config.PORT, () => {
  // eslint-disable-next-line no-console
  console.log(`Moralis Server is running on port ${config.PORT}.`);
});
// This will enable the Live Query real-time server
ParseServer.createLiveQueryServer(httpServer);
#5

You’re still getting the same Could not POST to error from the SDK? Did you try with a normal POST request to /webhook?

console.log(req.body) // Call your action on the request here
console.log(“Handled!”)

Are you getting these logged? By return a message I mean send a response back e.g.

res.send('webhook response');
res.status(200).end() // Responding is important
#6

Added a res.send() and I’m not getting it. Even Postman requests aren’t going through.

#7

You have to start a local server that will handle those requests, and you have to return status code 200 for those requests

#8

Yep I started a local server and made it live using ngrok, also responding with status 200. Still not going through.

#9

Make a simple request to that webhook url to see how it works

#10

Here it says status code 404

#11

I did some tweaking and now I’m getting Error 422 (unprocessable entity).
MoralisError [Moralis SDK Core Error]: [C0006] Request failed, Unprocessable Entity(422): Validation Failed {"id":{"message":"Not match in '[0-9A-Fa-f]{8}-[0-9A-Fa-f]{4}-4[0-9A-Fa-f]{3}-[89ABab][0-9A-Fa-f]{3}-[0-9A-Fa-f]{12}'","value":"undefined"}}

Is this something to do with how I’m adding the stream? (I’ve posted the code above). The message says id: Not match, so it’s possibly something to do with that.

Also, in my ngrok status I’m now getting status 200, so it seems to be going through.

#12

You can use the swagger interface directly to add a stream

#13

This is the swagger interface:
https://api.moralis-streams.com/api-docs/

#14

Something is missing in my url: 'https://api.moralis-streams.com/streams/evm/undefined/address',. That was the same issue in the message. Any idea why that’s coming undefined?

#15

That should be the id of the stream that was created, where is that undefined.
After you create a stream you have to add an address to it

#16

Hey so I just checked my Moralis Dashboard and streams were successfully added. Also, I changed my syntax from:

    await Moralis.Streams.addAddress({
        id: stream.id,
        address: "0x24290447ee215bb2565F53e1c6092BA8b1E0CC84"
    })

to:

    const {id} = stream.toJSON()
    const address = "0x24290447ee215bb2565F53e1c6092BA8b1E0CC84"

    await Moralis.Streams.addAddress({address, id})

and now the error stops showing up.

However, the streams which are added now aren’t showing up on my dashboard (I guess the one’s which are already there are one’s I created from all my testing). Do newly created streams take time to show up in the dashboard?

#17

I would expect that all the streams will how in the dashboard, you can use the swagger interface to check the list of available streams too

try a hard reset to the browser window also

#18

All working and uploading on time! Thank you so much! Hopefully this will help others new to creating streams!
