Number of arguments error

Sophia Smart Contract Development
1

I have a smart contract call that was returning an empty error, then I did a dry run to get a more specific error, and I got incorrect number of arguments error which is really weird, as I am passing the correct number of arguments (9)!
Sophia function that I am calling is:
public stateful entrypoint finalize(pubkey: address, sig: signature, logicVersion : int, nonce : int, functionName : string, ti : int, flancer : int, flancersScore : int, flancersText : string) =
…
(so as can be seen it takes 9 arguments)

And in js code I call it like this in a try block:
const resBc = await _contract.methods
.finalize.get(req.body.publicKey, req.body.sig, req.body.logicVersion, req.body.nonce, ‘finalize’, task.bcId, freelancer.bcId, req.body.rate, req.body.message);

I catch error and print exact calling arguments:
console.error(req.body.publicKey, req.body.sig, req.body.logicVersion, req.body.nonce, ‘finalize’, task.bcId, freelancer.bcId, req.body.rate, req.body.message);
console.error(err);

And I get output:
ak_M65JLCoTNWEiprJT9oTZWrhs5bJJ8mg9SyEdcm3UqW6snTmxK 3f2c42a32835f7fb6519b739c274e8304380d353f38e7b853cef297410cede60664e91ca6ea61aedef2f075749d95fadd29d17eef3154fdb2ef86781249ebc08 1 9 finalize 4 2 2 soso
Error: Invocation failed: cb_RXhwZWN0ZWQgOSBhcmd1bWVudHMsIGdvdCA4ls17fg==. Decoded: Expected 9 arguments, got 8��{~
…
returnType: ‘error’,
returnValue: ‘cb_RXhwZWN0ZWQgOSBhcmd1bWVudHMsIGdvdCA4ls17fg==’,
error: ‘cb_RXhwZWN0ZWQgOSBhcmd1bWVudHMsIGdvdCA4ls17fg==’,
decodedError: ‘Expected 9 arguments, got 8��{~’

So super weird…any ideas? @philipp.chain @bruteforce.chain @hanssv.chain
Is there some limit in Sophia on the number of arguments or size of all arguments combined? I am sure there are, but it would be weird if that limit was only 8 arguments :confused: (actually I tested the function through online Sophia IDE and it worked, so I don’t get what’s wrong with my JS calling procedure)

what sdk version are you using?

@philipp.chain updated to 7.7.0 but still getting the same error…there is now rlpEncoded field as well so I will paste the error output in case you find it useful:

can you provide me with an sample project to reproduce the error, the following works well for me:

const {Universal, MemoryAccount, Node} = require('@aeternity/aepp-sdk');

const keypair = {
  secretKey: "",
  publicKey: ""
};

const config = {
  url: 'https://testnet.aeternity.io/',
  internalUrl: 'https://testnet.aeternity.io/',
  compilerUrl: 'https://latest.compiler.aepps.com'
};

const getClient = async () => {
  return Universal({
    nodes: [{
      name: 'testnet',
      instance: await Node(config)
    }],
    accounts: [MemoryAccount({keypair: keypair})],
    networkId: 'ae_uat',
    compilerUrl: config.compilerUrl
  });
};

const source = `
contract Test =
  entrypoint finalize(pubkey: address, sig: signature, logicVersion : int, nonce : int, functionName : string, ti : int, flancer : int, flancersScore : int, flancersText : string) =
    (pubkey, sig, logicVersion, nonce, functionName, ti, flancer, flancersScore, flancersText)
`;


const deploy = async () => {
  const client = await getClient();
  const contract = await client.getContractInstance(source);
  console.log(await contract.deploy())

  const finalize = await contract.methods.finalize(
    "ak_M65JLCoTNWEiprJT9oTZWrhs5bJJ8mg9SyEdcm3UqW6snTmxK",
    "3f2c42a32835f7fb6519b739c274e8304380d353f38e7b853cef297410cede60664e91ca6ea61aedef2f075749d95fadd29d17eef3154fdb2ef86781249ebc08",
    1, 9, "finalize", 4, 2, 2, "soso");

  console.log(finalize)
};

deploy();

Thanks. One thing that occurred to me is that i used Contracts Aepp for compiling and deploying and it might be using an outdated compiler? I will try now deploying using js sdk
In the meantime it’d be great if you can try calling the actual function, and see what we get…the contract is deployed on testnet at ct_2bo1vBzK7jSCE26wd8KGHev7iJ3hFCB8c2r3G4xRcoWbkY9wBn
This is the actual function body:
//client accepts flancer’s work
public stateful entrypoint finalize(pubkey: address, sig: signature, logicVersion : int, nonce : int, functionName : string, ti : int, flancer : int, flancersScore : int, flancersText : string) =
require(functionName == “finalize” && Crypto.verify_sig(String.blake2b(String.concat(Int.to_str(logicVersion), String.concat(Int.to_str(nonce), String.concat(functionName, String.concat(Int.to_str(ti), String.concat(Int.to_str(flancer), String.concat(Int.to_str(flancersScore), flancersText )))))) ), pubkey, sig) && logicVersion == state.logicVersion && nonce == state.nonces[pubkey=0], “Wrong function name, nonce, logicVersion or failed signature check” )

    let (profile, pi) = getMyProfile(pubkey)
    let task = state.ct_store.getTask(ti)
    require(task.client == pi, "You can only finalize applications on your own tasks")
    require(task.applicationStage[flancer=999] == 1, "This freelancer is not working on this task")

    state.ct_store.setTaskApplicationStage(ti, flancer, 2)
    state.ct_store.setTaskMstoneStage(ti, flancer*10, 2)

    let fi = state.ct_store.getLastFeedbackIndex() + 1
    require(flancersScore >= 1 && flancersScore =< 5 && flancersText != "", "Feedback score must be 1 to 5 and text non empty")
    state.ct_store.setFeedback(fi, ti, flancer, 0, "", flancersScore, flancersText, 1)
    state.ct_store.setLastFeedbackIndex(fi)
    state.ct_store.setTaskFeedback(ti, flancer, fi)
    let profileFlancer = state.ct_store.getProfile(flancer)
    state.ct_store.setProfileFlancerScore(flancer, profileFlancer.flancerScore + flancersScore)
    state.ct_store.setProfileFlancerNumJobs(flancer, profileFlancer.flancerNumJobs + 1)

    put(state{nonces[pubkey] = state.nonces[pubkey=0] + 1})

also seems to work for me, receiving “Wrong function name, nonce, logicVersion or failed signature check”

const {Universal, MemoryAccount, Node} = require('@aeternity/aepp-sdk');

const keypair = {
  secretKey: "",
  publicKey: ""
};

const config = {
  url: 'https://testnet.aeternity.io/',
  internalUrl: 'https://testnet.aeternity.io/',
  compilerUrl: 'https://latest.compiler.aepps.com'
};

const getClient = async () => {
  return Universal({
    nodes: [{
      name: 'testnet',
      instance: await Node(config)
    }],
    accounts: [MemoryAccount({keypair: keypair})],
    networkId: 'ae_uat',
    compilerUrl: config.compilerUrl
  });
};

const source = `
contract Test =
  public stateful entrypoint finalize : (address, signature, int, int, string, int, int, int, string) => int
`;


const deploy = async () => {
  const client = await getClient();
  const contract = await client.getContractInstance(source, {contractAddress: "ct_2bo1vBzK7jSCE26wd8KGHev7iJ3hFCB8c2r3G4xRcoWbkY9wBn"});
  //console.log(await contract.deploy())

  const finalize = await contract.methods.finalize.get(
    "ak_M65JLCoTNWEiprJT9oTZWrhs5bJJ8mg9SyEdcm3UqW6snTmxK",
    "3f2c42a32835f7fb6519b739c274e8304380d353f38e7b853cef297410cede60664e91ca6ea61aedef2f075749d95fadd29d17eef3154fdb2ef86781249ebc08",
    1, 9, "finalize", 4, 2, 2, "soso");

  console.log(finalize)
};

@philipp.chain thanks Piwo!
I figured it out, the error actually happens inside the body of the function, at line:

state.ct_store.setFeedback(fi, ti, flancer, 0, "", flancersScore, flancersText, 1)

There 8 arguments are passed, and I forgot I changed that function in the store contract to take 9 arguments. It’s incredible coincidence that both functions are supposed to take 9 arguments which made this issue confusing :smiley:
Would it be possible to have instead of just decoded error some way to get the line at which it was thrown and stack trace? Or any other ideas?
