I donāt know, you can try with the other number
just did, itās still failing
you can try to add the event sync from admin interface
Iāve been trying, but itās not accepting the abi for some reason. Iāll try it out again
what is the abi that you are using?
the example of one eventās abi is
{
"anonymous": false,
"inputs": [
{
"indexed": true,
"internalType": "address",
"name": "seller",
"type": "address"
},
{
"indexed": true,
"internalType": "address",
"name": "nftAddress",
"type": "address"
},
{
"indexed": true,
"internalType": "uint256",
"name": "tokenId",
"type": "uint256"
},
{
"indexed": false,
"internalType": "uint256",
"name": "price",
"type": "uint256"
}
],
"name": "NFTListed",
"type": "event"
},
Iāve tried pasting the entire abi, part of the abi, it still does not allow me to access the Topic
this is all you paste as the ABI?
no, Iāve tried pasting the entire abi, part of the abi, it still does not allow me to access the Topic

Try with the legacy interface: https://legacybackup.moralis.io/, the legacy interface will not stay for long.
you need only the abi for the event that you want to sync, but in the right format
the interface says āPaste the whole ABI or just the event object of the contractā so Iāve tried both options, and still the same result.
The format I use is json, is it supposed to be something else?
it should have the proper start and ending, not random , or other things like
Could you give me an example ?
Itās the first time I have to do this, so Iāve tried removing the abi in front, removing brackets, etcā¦ but it doesnt work
anonymous": false,
"inputs": [
{
"indexed": true,
"internalType": "address",
"name": "nftAddress",
"type": "address"
},
{
"indexed": true,
"internalType": "uint256",
"name": "tokenId",
"type": "uint256"
}
],
"name": "NFTDeleted",
"type": "event"
Thatās what appears in the .json file that has the abi in it, Iām not sure how to format it
the syntax is different when you use it in the admin interface vs when you use it from a script to add an event sync
when you add it from the interface you will need [ at the beginning and ] at the end, and the abi only for your specific event should be enough inside those [ ]
nothing more, no extra , no other things before and after
alright, so [ inputs, name, type] only as data inside those brackets, correct?
no, you have to update this one a little, add [ ], remove a , and that should be all
ooook, finally got it, thank you!!! now it allows me to access the topic and save it.
Iāll keep you updated on how it goes now

Thanks again for your help! running mint-and-list correctly lists my NFT and I can see it on the dashboard.
Iāll keep looking at this eth_blockNumber counter running wild, there may be some event listener stuck on a loop or something. Probably has to do with my code, but at least I can move forward with my dapp.
Iāll also investigate why the script is not working, just 'cause.
Thanks again, you were very helpful
