  • Hi dev! Welcome to Ethereum Stackexchange! Please include the contract code and the code calling the contract as text, so it is easier to debug.

There could be multiple reasons for that. But: Have you checked if the abi of the contract object contains the function you are trying to use? Happens to me all the time that I add a function in the contract and forget to update the abi for web3.js.

Or: Are you sure it's not balanceOfContractFunc() instead of balanceOfContractfunc() ?

Check your ABI as swisstackle mentioned above, if you call it through remix and it works then it should work also through web3 js if the ABI is up to date.
