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: Unable to add a transaction to blockchain despite the successful message setting
As a developer, it is frustrating if it is unable to make it clear, only to find out later that there is a logical error in the code. In this article, we are immersed with interaction with Metamask and its messaging system.
The problem: Setting a message through Remix here
When developing a remix project, you can set a message using SetMessage (Str)
. This method is used to store data that are displayed in Blockchain Explorer or other places where the messages appear. The problem arises when trying to use this function with Metamask.
The problem: Failed to add the transaction despite setting a successful message
When calling the “setmessage ()” feature, we expect a transaction to log a transaction into the blockchain. Surprisingly, however, there is no error message in Blockchain Explorer or other places. In addition, when you try to retrieve the message using the getmessage ()
method, we find that there is no value returned.
The connection: Remix here and Metamask
To understand the question better, let’s examine how the remix works with Metamask. In a remix project, you can use the setmessage (str) feature to set the Blockchain Explorer or other places where the messages appear. However, if Metamask interacts with the blockchain, the message setting function seems to work differently.
Debugation and troubleshooting
We follow these steps to troubleshoot the problem:
- Check the Remix console output: In the Remix project, go to the Remix Studio “console” tab (Remix here) or use the command line to check the errors related to Metamask.
- Check the “setmessage ()” and
getmessage ()" methods: Check out the codes of both functions of the Metamask JavaScript module. Check that there are differences between the two methods, such as asynchronous behavior or error handling.
- Test it with different messages: Try to set different types of messages (such as strings, numbers) to examine, have an effect on "setmessage ()" andgetmessage ()
functionality.
Conclusion
The question is not about the underlying blockchain technology, but rather how Metamask works with the messaging system in the remix. Despite the fact that the message is set through thesetmessage (), the error message or the transaction log does not appear to interact with the blockchain when using Metamask.
To solve the problem, you need to examine the code "setmessage ()" andgetmessage ()” and verify that they work as expected. In addition, test different messages to determine that there is a special type of data that trigger the problem.
Example Code
Here’s an example of how to use setmessage ()
in the remix project:
`Javascript
{Message} import from "Web3";
Const Message = "Hello, World!"; // string
// Set the message using Setmessage Function
Message.set ();
And here’s a sample code detail to set the message through getmessage ()
:
`Javascript
{Message} import from "Web3";
Import {remixContract} from "./remixcontract";
Const Contract = New Remixkontrast ();
Contract.setmessage (message); // string
In this example, we define a “message” variable as a string and use “setmessage ()” to set it. Then we call the “Getmessage ()” method to retrieve the value.
If you follow these steps and check that there is a difference between the “setmessage ()” and “getmessage ()” features in the Metamask JavaScript module, you should be able to diagnose and solve this problem.
