Understanding the error: Why deployment.js returns Factory Runner does not support transmission of events"
As a developer who uses Hardhat with the Alchemy application for an intelligent contract, you are likely to face an error when trying to enable contracts. The special error message "Factory Runner does not support the transmission of events (Operation =" Sendtransaction ") shows that there is a problem in the event mechanism used by the Deploy.JS command series.
Context: Start.js and Alchemy API
Deploy.js is a popular JavaScript library to introduce smart contracts for different Blockchain networks, including Ethereum. It provides a convenient way to interact with contracts introduced with its high -level application interface.
The Alchemia application interface, on the other hand, provides a solid application for interaction with Blockchain information, including contract management. Hardhat uses the deployment environment as a development environment.
Error Explanation
When the deployment.js tries to send events with a factory runner, it will face an error because Alchemy API does not support this mechanism to Ethereum. The factory runner is designed to handle more complex functions, such as the introduction of contracts, the creation of wallets, and the control of the roads on a particular network. However, sending events, especially "Sendtransaction", is not one of its features.
troubleshooting stages
To solve this problem, follow these steps:
- Check alchemy's API settings : Make sure you are using the correct API terminal in Ethereum (eg "https: // mainnet.infura.io/v3/v3/your_project_id) and supports the necessary functions.
- Make sure the deploy.js version
: Check if you use an outdated version of deploy.JS, as newer versions may have fixed problems associated with transaction support.
- Try a different transaction method : Instead of trying to send events with deploy.JS, try to call other API endpoints, such as
Eth_Accounts, who return the Ethereum network status list.
Updated deployment.js code
Here’s an example of how to edit your deployment.js command series to use a different event method:
`Javascript
Const {alchemy} = insist (‘@alchemy-api’);
Const Client = New Alchemia ({
// Infura Project ID and API key
});
customer
.eth_accounts ()
.Hen ((accounts) => {
Console.log (accounts);
})
.Catch ((error) => {
Console.error (error);
});
`
In this updated code, we use the eth_accounts () method to apply for a list of the Ethereum network accounts. This allows us to avoid trying to send events on deployment.JS.
conclusion
By following these faults and updating the Deploy.JS command series, you should be able to solve the error and successfully introduce contracts to the Ethereum network using the Alchemy application subscription with Hardhat. Be sure to check the Alchemy API settings and check the updates to the Deploy.JS library before making more changes in your code.
