未捕获（承诺中）错误：返回的值无效，它是否耗尽了 Gas？ （在本地工作，但不在 Ropsten 上工作）

Question

从我的一个 Solidity 智能合约调用仅视图函数时，我在 web3js 中遇到错误。奇怪的是，它可以在本地测试网络（通过 Ganache 运行）上运行，但是当我将合约部署到 ropsten 测试网络时，fall 函数失败并出现以下错误：

Uncaught (in promise) Error: Returned values aren't valid, did it run Out of Gas?

在此声明之后我还收到另一个错误：

Denying load of chrome-extension://nkbihfbeogaeaoehlefnkodbefgpgknn/sourcemaps/inpage.js.map. Resources must be listed in the web_accessible_resources manifest key in order to be loaded by pages outside the extension.

可能相关也可能不相关。

导致错误的前端代码是：

for (var i = 0; i < userDetails[0]; i++) {
            console.log(i)
            var contractAddress = await trsContract.methods.getUserContract(i).call()
            console.log(contractAddress)
            contractAddresses.push(contractAddress)
        }

我正在使用以下依赖项

    "@material-ui/core": "^4.5.2",
    "material-ui": "^0.20.2",
    "react": "^16.11.0",
    "react-dom": "^16.11.0",
    "react-router-dom": "^5.1.2",
    "react-scripts": "3.2.0",
    "react-spinners": "^0.6.1",
    "validator": "^12.0.0",
    "web3": "^1.2.2"

Answer 1

您是否使用正确的合约地址启动了 trsContract？

地址设置错误会报错。
