How many functions allowed per contract? + solidity

Question

I deployed a contract to ropsten and tried to call a method from frontend, but was getting

TypeError: Cannot read property 'call' of undefined

So I checked my instance via this.Test.deployed().then((instance) => { console.log(instance) } to see if I have the function, but this particular function was not there!

It's a public view returns function that returns a boolean. I have several public view returns functions in the contract, but I have no idea why this one was omitted. I didn't even get an error while creating a contract to ropsten. Is there a limit or something?

** Edit **

From Frontend:

  checkPrizeReceived(id: number, price: number): Promise<any> { 
    this.Test.setProvider(this.web3.currentProvider); 
    return this.Test.deployed().then((instance) => {
      console.log(instance)
        return instance.checkPrizeReceived.call(id, price);
    })
    .then((value) => {  
      return value;
    })
    .catch((e) => {
        console.log(e);
    });
  }

Solidity:

  function checkPrizeReceived(uint256 id, uint price) public view returns (bool) {
    for (uint i = 0; i < better[msg.sender].length; i++) {   
      if (better[msg.sender][i].id == id && better[msg.sender][i].price == price) {
        if (better[msg.sender][i].receivedPrize) {
          return true;
        }
      }
    }

    return false;
  }

The problem can be with "web3". Check what version of web3 you using.

In version 1.0 the calling contract is with .call() method https://web3js.readthedocs.io/en/1.0/web3-eth.html#id74

In version 0.2.x.x, you can call methods directly from contract instance

myContractInstance.myMethod(param1 [, param2, ...] [, transactionObject] [, defaultBlock] [, callback]);

Documentation for 0.2 version is here https://github.com/ethereum/wiki/wiki/JavaScript-API

There's no such thing as a maximum number of functions, just the maximum amount of gas per block, which includes in any case the whole bytecode of the contract.

First, if the function is not in the ABI but it's in your solidity code, you'll have to recompile and regenerate the ABI (and possibly redeploy the contract). If there are no errors during the process the function should be in the ABI this time.

Second, I think you are accessing the function in the wrong way. It should be as follows:

instance.checkPrizeReceived(id, price).call({from: "0x.........."});
