报错Error: Returned values aren‘t valid, did it run Out of Gas?

 

用web3部署一个简单的获取状态变量的值的合约。获取状态变量值报错

index.js:298 Uncaught (in promise) Error: Returned values aren't valid, did it run Out of Gas? You might also see this error if you are not using the correct ABI for the contract you are retrieving data from, requesting data from a block number that does not exist, or querying a node which is not fully synced.

主网没部署合约，所以调用合约出错了，相当于查找不到这个合约，注意自己合约部署网络
