Describe the Problem
Use ABI from https://etherscan.io/address/0x7fC77b5c7614E1533320Ea6DDc2Eb61fa00A9714
simplify a bit and just use code as follow
export const abi = [ {
"name": "balances",
"outputs": [
{
"type": "uint256",
"name": ""
}
],
"inputs": [
{
"type": "int128",
"name": "arg0"
}
],
"constant": true,
"payable": false,
"type": "function"
},]
const contract = new Contract("0x7fC77b5c7614E1533320Ea6DDc2Eb61fa00A9714", abi as any, provider)
const func = contract.getFunction("balances(int128)")
const res = await func(0)
it will report:
Error: contract runner does not support sending transactions (operation="sendTransaction", code=UNSUPPORTED_OPERATION, version=6.2.2)

}
the fragment is like this:
If I manually add "stateMutability": "view", to the ABI, then
notice the constant field of the fragment become true
