Got error in CloudFucntions Web3 call [SOLVED]

[cryptokid]

You say that it worked fine before 4-5 hours ago?

[DmKodOff]

Yes…

now i update the old server 0.0.260 to new for check the error… and get the same error on web3 call in cloud function (

[cryptokid]

This code works fine in particular for me:

Moralis.Cloud.define("test_web3", async (request) => {
  const web3 = Moralis.web3ByChain('0x38')
  const abi = [{"constant":true,"inputs":[],"name":"name","outputs":[{"name":"","type":"string"}],"payable":false,"stateMutability":"view","type":"function"}]
  address = "0x2170Ed0880ac9A755fd29B2688956BD959F933F8"
    const contract = new web3.eth.Contract(abi, address)
    const name = await contract.methods
      .name()
      .call()
      .catch((e) => logger.error(`callName: ${e}${JSON.stringify(e, null, 2)}`))
    return name;
    
});

But with some variations on the address will not work any more.

@DmKodOff

Invalid JSON RPC response: “Unauthorized”{}

i get for all request(

[cryptokid]

if you try from another server, you get same error?

[DmKodOff]

after update the server get the same

[cryptokid]

I mean for a totally different server, if you run that cloud function if it works

[DmKodOff]

it works before well … i don’t touch any thing…
later check that don’t have some datas…
come to check the server and see - the server updated and make errors…

)
i check other dev server with same function and there all was fine. all work correct.

I upgrade the server there for check. and the function get the same error… after that )

const ContractCall = async (abi, address) => {
  try {
    const web3 = Moralis.web3ByChain('0x38')
    const contract = new web3.eth.Contract(abi, address)
    const name = await contract.methods
      .name()
      .call()
      .catch((e) => logger.error(`callName: ${JSON.stringify(e, null, 2)}`))
    const symbol = await contract.methods
      .symbol()
      .call()
      .catch((e) => logger.error(`callSymbol: ${JSON.stringify(e, null, 2)}`))
    const totalSupply = await contract.methods
      .totalSupply()
      .call()
      .catch((e) =>
        logger.error(`call_TotalSupply: ${JSON.stringify(e, null, 2)}`)
      )
    const decimals = await contract.methods
      .decimals()
      .call()
      .catch((e) =>
        logger.error(`call_decimals: ${JSON.stringify(e, null, 2)}`)
      )

    return { name, symbol, totalSupply, decimals }
  } catch (e) {
    logger.error(`web3ERORr: ${e} ${JSON.stringify(e, null, 2)}`)
    return null
  }
}

here the full code of function

[DmKodOff]

the problem come on 24 Sept 2021 at 09:15:49 UTC
but it can just upgrade the server at that time.
I’m surprised why it upgrade automatically.
maybe I can downgrade it in some way?

here is the server, if it helps )

[cryptokid]

Just to remove other possible problems, if you add this cloud function and run it you get same error?

Moralis.Cloud.define("test_web3", async (request) => {
  const web3 = Moralis.web3ByChain('0x38')
  const abi = [{"constant":true,"inputs":[],"name":"name","outputs":[{"name":"","type":"string"}],"payable":false,"stateMutability":"view","type":"function"}]
  address = "0x2170Ed0880ac9A755fd29B2688956BD959F933F8"
    const contract = new web3.eth.Contract(abi, address)
    const name = await contract.methods
      .name()
      .call()
      .catch((e) => logger.error(`callName: ${e}${JSON.stringify(e, null, 2)}`))
    return name;
    
});

[DmKodOff]

same

callName_test_web3: Error: Invalid JSON RPC response: “Unauthorized”{}

[DmKodOff]

@cryptokid Did you get a response on this CF ?

[cryptokid]

It looks like it doesn’t work on latest server version, it will get fixed. I tested on an older server version.

[DmKodOff]

do you know some way to downgrade version?
Im 1 am now…
I will glad to fix that and go to push(pillow)

[cryptokid]

Work around:

Moralis.Cloud.define("test_web32", async (request) => {

  web3 = new Moralis.Web3(new Moralis.Web3.providers.HttpProvider("https://speedy-nodes-nyc.moralis.io/YOUR_ID_HERE/bsc/mainnet"));
const abi = [{"constant":true,"inputs":[],"name":"name","outputs":[{"name":"","type":"string"}],"payable":false,"stateMutability":"view","type":"function"}]
  address = "0x2170Ed0880ac9A755fd29B2688956BD959F933F8"
    const contract = new web3.eth.Contract(abi, address)
    const name = await contract.methods
      .name()
      .call()
      .catch((e) => logger.error(`callName: ${e}${JSON.stringify(e, null, 2)}`))
    return name;    
});
