EIP-1898 not support. For the graph node required.

[ronit9586]

i want to know gatchain evm support EIP-1898 ?
i want to fetch data from gatechain smart contract in subgraph but it is getting faild.

This is the function in subgraph:

export function fetchTokenSymbol(tokenAddress: Address): string {
  // hard coded override
  if (tokenAddress.toHexString() == ETH_ADDRESS) {
    return 'ETH'
  }
  if (tokenAddress.toHexString() == '0xe0b7927c4af23765cb51314a0e0521a9645f0e2a') {
    return 'DGD'
  }

  let contract = ERC20.bind(tokenAddress)
  let contractSymbolBytes = ERC20SymbolBytes.bind(tokenAddress)
   
  // try types string and bytes32 for symbol
  let symbolValue = 'unknown'
  let symbolResult = contract.try_symbol()
  if (symbolResult.reverted) {
    let symbolResultBytes = contractSymbolBytes.try_symbol()
    if (!symbolResultBytes.reverted) {
      // for broken pairs that have no symbol function exposed
      if (!isNullEthValue(`0x${symbolResultBytes.value.toHexString()}`)) {
        symbolValue = symbolResultBytes.value.toString()
      }
    }
  } else {
    symbolValue = symbolResult.value
  }

  return symbolValue
}

Continuously getting this Error on the graph node :

This issue is reported here in the graph node github : graphprotocol/graph-node#2319

this is the answer please some one help me out how can i found such gatechain RPC node which support EIP-1898.

Please someone help me out in this.
