Sync events on local dev chain

SachaH · October 13, 2021, 12:12am

Hi,

So yesterday I was working on my local dev chain, it was connected to Moralis as confirmed within the interface and everything was working fine (even the events).
But today I’ve spent 2 hours trying to configure sync events on my local dev chain but it doesn’t work now, for no obvious reasons…
I checked within a hardhat script and I do have events emitted, I configured the right address in the sync contract event. I also recreated new ones, but nothing seems to work…
By the way as of now, it is not possible to directly edit fields within the sync events interface since it’s always blocked by the tableName (tableName already in use)…

{
  "anonymous": false,
  "inputs": [
    {
      "indexed": false,
      "internalType": "address",
      "name": "_auditor",
      "type": "address"
    },
    {
      "indexed": true,
      "internalType": "address",
      "name": "_auditorOwner",
      "type": "address"
    }
  ],
  "name": "auditorRegistered",
  "type": "event"
}

auditorRegistered(address, address)

Hi,
You’ll have to create another event that doesn’t use field names that start with that _. You’ll have to change that abi that you paste there so that name fields don’t start with _.

Hi,

The problem with “_” can be fixed by just adding a beforeConsume hooks in cloud functions and replacing “_auditor” by “auditor”.
Source : Sync and Watch Contract Events plugin : Event data not being registered

Moralis.Cloud.beforeConsume('AuditorRegistered', async (event) => {
  event.auditor = event._auditor.toLowerCase();
});

Everything was working fine so maybe it’s something else.

Just to be sure I tried again and changed the contract event parameters names, recreated a sync events (with new abi, address, etc…) and I still get the same problem.

{
  "anonymous": false,
  "inputs": [
    {
      "indexed": false,
      "internalType": "address",
      "name": "auditor",
      "type": "address"
    },
    {
      "indexed": true,
      "internalType": "address",
      "name": "auditorOwner",
      "type": "address"
    }
  ],
  "name": "auditorRegistered",
  "type": "event"
}

now it is preferred to modify the abi instead of using beforeConsume.

Anyway, it should work with the abi that you pasted here, can you also paste your server url?

SachaH · October 13, 2021, 12:28pm

Yes here it is https://vxriy2xhi2ya.moralishost.com:2053/server

SachaH · October 13, 2021, 12:32pm

Oh and btw you will see that the table name is now AuditorRegisteredd, as it is not possible to edit without creating a new table

cryptokid · October 13, 2021, 12:35pm

Yep, I’m used to add a letter at the end of the table name when I edit an event.

SachaH · October 13, 2021, 12:42pm

Hey so got any idea? It’s still not working on my side

cryptokid · October 13, 2021, 12:45pm

do you still use that Moralis.Cloud.beforeConsume hook? what happens if you remove it in case that you still use it

SachaH · October 13, 2021, 12:48pm

I just removed it but still nothing happens.

The beforeConsume hook is deprecated ?

cryptokid · October 13, 2021, 12:52pm

I think that the plan is to remove beforeConsume hook

SachaH · October 13, 2021, 12:55pm

Oh btw here is my debugger script in hardhat to verify the contracts emits events

const hre = require('hardhat');

async function main() {
  const [owner, client] = await hre.ethers.getSigners();

  const AuditorGenerator = await hre.ethers.getContractFactory(
    'AuditorGenerator',
  );
  const auditorGenerator = await AuditorGenerator.attach(
    '0x4A679253410272dd5232B3Ff7cF5dbB88f295319',
  );

  const Factory = await hre.ethers.getContractFactory('Factory');
  const factory = await Factory.attach(
    '0xa85233C63b9Ee964Add6F2cffe00Fd84eb32338f',
  );

  await auditorGenerator.createAuditor('Smart Lookup');

  const eventFilter = factory.filters.auditorRegistered(null, owner.address);
  const events = await factory.queryFilter(eventFilter);
  console.log(events.length > 0);
}

main();

The output is

true

So the events are emitted within my local dev chain, the local dev chain is connected to moralis as shown in the dashboard and the contract address, abi, topic are the right ones. I really don’t know what else I could do/check.

Here is one of the event I should catch (displayed within the hardhat script

you could restart the server, try to save again the event with a different table name, but it is not sure that it will solve the problem.
also, some problems could appear if you reuse your Moralis server with different instance of local devchain, like making transactions until block 36 and then resetting back to block 0 the local devchain and starting to make transactions again
also you have to choose historical sync when you sync those events

SachaH · October 13, 2021, 1:01pm

Already tried to restart the server but i will do it once again to be sure.
I don’t understand what you said about “reuse your Moralis server with different instance of local devchain”, I just start my hardhat dev chain, redeploy my contracts on it and then connect it to moralis that’s all, should I be doing something else ?
And yes I always check sync historical!

SachaH · October 13, 2021, 1:02pm

Restart didn’t solve the problem

cryptokid · October 13, 2021, 1:06pm

how do you do this part, you reuse a previous blockchain transaction history or you start again from block 0?

SachaH · October 13, 2021, 1:07pm

No I don’t save the state of the local dev chain is that a problem?
How am i supposed to do it?
Can I reset to block 0 on Moralis to fix it ?

SachaH · October 13, 2021, 1:08pm

Every work session I just restart a new chain, redeploy my contracts, and then link with moralis using frp and after I change the contract addresses in sync event tab.

cryptokid · October 13, 2021, 1:09pm

restart a new chain = a new chain with 0 transactions?

SachaH · October 13, 2021, 1:10pm

I guess that restarting a new chain on Hardhat starts it frrom block 0 since my contracts are not deployed anymore when I restart.
