[SOLVED] Failing watchContractEvent

Moralis General
#1

Hi,

I am attempting to setup an event sync via a node script but getting { success: false } as response.

Here is the script that I’m using:

require('dotenv').config()

const Moralis = require("moralis-v1/node");

const serverUrl = process.env.MORALIS_SERVER_URL;
const appId = process.env.MORALIS_APP_ID;
const masterKey = process.env.MORALIS_MASTER_KEY;

const cmdArgs = process.argv.slice(2);

if(!cmdArgs[0]) {
    throw Error("Contract address not provided");
}

const watchContractEvents = async () => {
    await Moralis.start({ serverUrl, appId, masterKey });
    
    let options = {
        chainId: "0x89",
        address: cmdArgs[0],
        topic: "TokenMinted(uint256, address)",
        abi: {
            anonymous: false,
            inputs: [
                {
                    indexed: false,
                    internalType: "uint256",
                    name: "tokenId",
                    type: "uint256"
                },
                {
                    indexed: false,
                    internalType: "address",
                    name: "minter",
                    type: "address"
                }
            ],
            name: "TokenMinted",
            type: "event"
          },
        limit: 500000,
        tableName: "TokenMintedEvents",
        sync_historical: false,
    };

    let moralisRun = await Moralis.Cloud.run("watchContractEvent", options, { useMasterKey: true })
    console.log('moralisRun:', moralisRun);
};

watchContractEvents();

I’ve tried specifying the topic in hex format, but it result in the same failure. Hopeful that there’s something glaringly obvious that I’m missing.

Thanks in advance,
Yuri

I don’t see something obvious at a first look. does it work if you try to add it from the admin interface?

#3

Maybe try to use console.log with the parameters from options to see if everything looks like expected

#4

Yes, I set up a sync form the dashboard and it works as expected.

#5

Get this in the dashboard logs:

2022-09-12T17:57:07.985Z - Ran cloud function watchContractEvent for user undefined with:
  Input: {"chainId":"0x89","address":"0xf12F97dc64d59ac7586B0C3dE67f4ef97fEe9349","topic":"TokenMinted(uint256, address)","abi":{"anonymous":false,"inputs":[{"indexed":false,"internalType":"uint256","name":"tokenId","type":"uint256"},{"indexed":false,"internalType":"address","name":"minter","type":"address"}],"name":"TokenMinted","type":"event"},"limit":500000,"tableName":"TokenMintedEvents","sync_historical":false}
  Result: {"success":false}
#6

you still need to make this work from code now?

#7

The log output from above was with trying to create it from code, so yes - still need to get that working

#8

what is the server url?

#9

Is that the same as Dapp URL?
Dapp URL is: https://1nvxhrqd4tbl.usemoralis.com:2053/server

#10

this was the error:

Error: No provider found for chain 0x89

It looks like that server doesn’t have that specific chain enabled

#11

My bad! It should be 0x13881 for Mumbai.

Apologies - can I ask where you found that error so I can check there next time I run into something similar?

#12

you don’t have access to that error, you couldn’t find it

#13

Got it - thank you for your help, it works now that I have the right chainId.
