  This error usually occurs when you try to call a function that doesn't exist in the smart contract. Make sure you have the correct function name and that it is defined in the contract. Additionally, check if the function is marked as public or external, as private functions cannot be called from outside the contract. If the function is part of a library, make sure the library is imported correctly. Finally, check if the function requires any arguments and if you are passing them correctly when calling the function.

  Ah, the 'at is not a function' error. It's a common issue in cryptocurrency smart contracts. One possible reason for this error is that you're trying to call a function that doesn't actually exist in the contract. Double-check your function names and make sure they match exactly. Another reason could be that the function you're trying to call is marked as private, which means it can only be accessed within the contract itself. If you're calling it from outside the contract, you'll need to change the visibility to public or external. Lastly, make sure you're passing the correct arguments to the function, if any are required. Hope that helps!
