[SOLVED] Can't get return value from executeFunction

Moralis General
#1

Hello!

I have next code:
const abi = [
{
“inputs”: [
{
“internalType”: “uint256”,
“name”: “biddingTime”,
“type”: “uint256”
},
{
“internalType”: “uint256”,
“name”: “revealTime”,
“type”: “uint256”
},
{
“internalType”: “address”,
“name”: “token”,
“type”: “address”
}
],
“name”: “newGame”,
“outputs”: [
{
“internalType”: “uint256”,
“name”: “id”,
“type”: “uint256”
}
],
“stateMutability”: “nonpayable”,
“type”: “function”
}
]
const newGame = async () => {
const options = {
contractAddress: contractAddress,
functionName: “newGame”,
abi: abi,
params: {
biddingTime: “1641793392”,
revealTime: “1642225392”,
token: “0xe9e7cea3dedca5984780bafc599bd69add087d56”
},
};
const web3 = await $moralis.enableWeb3();
const exec = await $moralis.executeFunction(options);
console.log(exec);
}

All work well, but there isn’t return value.
Result is (no returned id):

}

Can you tell me please, what could be wrong?

What do you expect to receive as a returned value?

#3

My contract is:

function newGame(
uint biddingTime,
uint revealTime,
address token
)
external
onlyOwner
returns (uint id)
{
_gameIds.increment();
uint gameId = _gameIds.current();
Game storage game = games[gameId];
game.id = gameId;
game.biddingEnd = block.timestamp + biddingTime;
game.revealEnd = game.biddingEnd + revealTime;
game.gameToken= token;
game.initialPrice = 0;
return gameId;
}

So, I expect to receive gameId.

#4

I don’t know now in what circumstances you can get that id. Usually you have to parse events to get a result, In case that events were used.

#5

So, why using “runContractFunction” I can get retirn value, but can’t change state of the contract?

#6

runContractFunction only calls read only functions, no transactions is sent/processed to the chain, the chain is only queried

#7

Thanx!
Should I use native Web3 Api to listen transaction events?
I didn’t found example with special Moralis API to do it.

#8

in that result that you pasted above, it also included events, but that transaction didn’t have events

#9

I’ve changed contract

event GameStarted(uint gameId);

function newGame(
uint biddingTime,
uint revealTime,
address token
)
external
onlyOwner
{
_gameIds.increment();
uint gameId = _gameIds.current();
Game storage game = games[gameId];
game.id = gameId;
game.biddingEnd = block.timestamp + biddingTime;
game.revealEnd = game.biddingEnd + revealTime;
game.gameToken = token;
game.initialPrice = 0;
emit GameStarted(gameId);
}

but anyway didn’t see any event in events list…

#10

how does the received data look now?

#11

I copied example from documentation:
const newGame = async () => {
const options = {
contractAddress: contractAddress,
functionName: “newGame”,
abi: contract[“abi”],
params: {
biddingTime: “1641793392”,
revealTime: “1642225392”,
token: “0xe9e7cea3dedca5984780bafc599bd69add087d56”
},
};
const exec = await $moralis.executeFunction(options);

exec.events is empty…

#12

can you paste the entire output, as you did on first post? you can also see here how to post code on forum: READ BEFORE POSTING - How to post code in the forum

#13

Sorry, of course.
But it didn’t change…

#14

maybe it still uses the previous smart contract and not the new one

#15

I’ve triple time called “truffle migrate --network testnet”

#16

on what network was that contract deployed?

#17

On the bsc testnet

I changed contract long time ago…

#18

it looks like that contract was not deployed today, so probably it doesn’t have the updated code with events

#19

You were wright!
after using --reset opitons I can see event in list!
Could you point to example of watching event&
