[SOLVED] Can't sync historical events

Technical Issue Reporting
#1

Hi,
I’m trying to Sync and Watch Contract Events.
I’ve made a simple toy example, a ERC721 with a custom event when a new token is minted

_chainId: rinkeby
_topic: itemCreated(uint256,string)
_abi:

{
  "anonymous": false,
  "inputs": [
    {
      "indexed": false,
      "internalType": "uint256",
      "name": "id",
      "type": "uint256"
    },
    {
      "indexed": false,
      "internalType": "string",
      "name": "tokenURI",
      "type": "string"
    }
  ],
  "name": "itemCreated",
  "type": "event"
}

_address: 0xfF03E5E0ccb1792EF14F58511dD00183EB6fb257

If I activate the sync, the new events are fetched, but I don’t get the historical ones.
Regards

Try to rename in the abi that field with id name to something else

#3

I tried but still it doesn’t sync historical events

#4

Is there something I can do?
Thanks

Hello, Hope you are doing well, I am a web3 developer, Moralisian…
I met one bug, I have read all forum messages but can not find answer.
I created server and setup sync historical event, but can not sync historical event, only sync new event.

#12

Did you tick or set sync_historical to true? Try deleting and creating it again.

#13

I will try now

#14

Can you give the address, ABI, topic, etc. you’re using? Try restarting your server too.

When I try syncing this with Sync_historical set to true, I get this error:

The historical data contains more than 500000 rows, If your use-case depends on this amount of data, contact us for a specialized proposal

Have a read here about this error.

Maybe you can add filters to bring the amount of data down.

thanks, but I need all that data, is there a method that can save all that data in my server?
and can I upgrade my account with crypto ( like BNB ) ?

#19

you can sync more data, you have to use event sync from code for that for now:
https://docs.moralis.io/moralis-dapp/connect-the-sdk/connect-using-node#add-new-event-sync-from-code

you can use that limit parameter to sync more

for upgrading, you can send an email to [email protected], you can ask there if you can pay with crypto
