这里是因为预编译合约没有abi文件导致的，可以暂时采用下面的方法：

precompiled合约的地址需要补齐，加0x前缀，长度为42个字符，0x00000000........5003
使用solc编译precompiled的接口声明文件 PaillierPrecompiled.sol
~/.fisco/solc/0.4.25/keccak256/solc --abi PaillierPrecompiled.sol

输出类似于下面：

Contract ABI JSON下面的内容为合约的ABI内容

在 console/contracts/.compiled/群组名/PaillierPrecompiled 目录下创建 mkdir 0x00000000........5003 目录(注意补齐长度为42字符)，然后创建文件PaillierPrecompiled.abi，然后将上面的ABI的内容拷贝至这个文件
console上重新调用合约，注意合约地址应该使用补齐后的地址
