When connect to the platform, and type 1 in the console, it shows a error such as

nc 127.0.0.1 20000
Can you make the isSolved() function return true?

[1] - Create an account which will be used to deploy the challenge contract
[2] - Deploy the challenge contract using your generated account

Hey, you need to modify the service.py such as

+ from hexbytes import HexBytes

- self._contract: Contract = Contract(build_json["abi"], build_json["bytecode"])
+ self._contract: Contract = Contract(build_json["abi"], HexBytes(build_json["bytecode"]))
