Metamask: Unable to add transaction to blockchain (I’m invoking the setMessage(str) method but the string i pass doesn’t get set but getMessage() method works)

Metamask: Failed to add event to Blockchain despite successful notification setting

As a developer, it is frustrating when you are unable to perform a seemingly simple operation, only to later discover that there is a logical error in your code. In this article, we will delve deeper into the Metamask issue and how it interacts with the messaging system.

Issue: Setting a message with Remix IDE

When working on your Remix project, you can set a message using the “setMessage(str)” function. This method is used to store information that is displayed in the blockchain explorer or other places where notifications are displayed. The issue occurs when trying to use this feature with Metamask.

Issue: Failed to add event despite successful notification setting

When we call the setMessage() function, we expect it to store an event on the blockchain. However, surprisingly, we do not see an error message in the blockchain explorer or other places where messages are displayed. Additionally, when we try to get the message using the “getMessage()” method, we notice that no value is returned.

Interface: Remix IDE and Metamask

To better understand this issue, let’s examine how Remix works with Metamask. In a Remix project, you can use the “setMessage(str)” function to set data in the blockchain explorer or other places where messages are displayed. However, when you use Metamask to interact with the blockchain, the notification setting function works differently.

Troubleshooting and Troubleshooting

To fix this issue, we do the following:

• Check the Remix console output: In your Remix project, go to the “console” tab in Remix Studio (Remix IDE) or use the command line to check for errors related to Metamask.

• Check the setMessage() and getMessage() methods: Review the code for both functions in the Metamask JavaScript module. Check for differences between the two methods, such as asynchronous operation or error handling.

• Try different messages: Try setting different types of messages (e.g. strings, numbers) to see if they affect the setMessage() and getMessage() functions.

Conclusion

The problem is not in the underlying blockchain technology, but in how Metamask interacts with the Remix messaging system. Despite setting the message using the setMessage() function, no error message or event log is displayed when Metamask is used to interact with the blockchain.

To fix this issue, review the code for the setMessage() and getMessage() functions and make sure they work as expected. Also, try different messages to see if a specific type of data is causing the problem.

Code example

Here is an example of how you can use the setMessage() function in your Remix project:

import { Message } from "web3";
const message = "Hello, world!"; // string
// Set the message using the setMessage function
message.set();

And here is an example code snippet for setting a message using the getMessage() method:

import { Message } from "web3";
import { RemixContract } from "./RemixContract";
const contract = new RemixContract();
contract.setMessage(message); // string

In this example, we define the variable “message” as a string and use the function “setMessage()” to set it. Then we call the method “getMessage()” to get the value.

After completing these steps and reviewing the differences between the setMessage() and getMessage() functions in the Metamask JavaScript module, you should be able to diagnose and resolve this issue.
