Multiple executeFunction calls cause MetaMask - RPC Error: Internal JSON-RPC error. 32005 rate limit exceed

Moralis General

Hello,

i just migrated from useDapp to moralis. im Using await Moralis.executeFunction(options). When doing this multiple times in a row, from time to time only sometimes for some reason, i get this inpage.js:1 MetaMask - RPC Error: Internal JSON-RPC error. 32005

Which seems to be related to a rate limit exceed.

I already did a lot of research. any ideas on this one? Thanks!

 const fetchPendingRewards = () => {
        if (walletAddress && isAuthenticated) {
            const fetch = async () => {
                const options = {
                    contractAddress: stakingAddress,
                    functionName: 'pendingReward',
                    abi: StakingContractProvider.abi,
                    params: {_user: walletAddress},
                }
                try {
                    // @ts-ignore
                    const response = await Moralis.executeFunction(options)
                    if (response && BigNumber.isBigNumber(response)) {
                        setPendingReward(Number(formatUnits(response, 18)))
                    }
                } catch (e) {
                    console.log('pendingReward', e)
                }
            }
            fetch()
        } else {
            setPendingReward(0)
        }
    }

#2

it looks like a rate limit error
a RPC url will be used to make those calls, the one that usually is added in metamask, and there has to be a rate limit for those RPC urls as if there will be no rate limit then someone could use it to make thousands of requests per second

#3

does this mean the problem might be caused by firing too many reuests? its only 8 in a row. tbis should be no problem right?

#4

It shouldn’t be a problem unless you’re making requests too quickly. How long does it take for all of them?

#5

fixed:

for reading we use

const response = await Moralis.Web3API.native.runContractFunction(options)

for writing we use

useWeb3ExecuteFunction()

using execute function for reading will use meta mask rcp which of course is limited
