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: You cannot add transaction to blockchain despite

As a developper, it is frustrating you cannot performation an act, that seems simple, ony to discover later, that a logical defect in you. In this article, we will be the problem with the Metamk and its interacting with the message.

The problem: configure a message throught Remix Ide

When you work on your Remix project, you can establish a message use SetMessage (STR) function. This method is used to get that information that in the blockchain explorer or outer place the messages aresages aresages are. The problem arises wen triing to smrefunction whe MetamSk.

** The problem: You cannot add transaction despite

When calling the Setmessage () function, we hope you register a transaction to the block. Howver, surprisingly, no error message is shown in In addition, wen triing to recover the message use Getmessage () method, we Find that no value is returned.

The connction: Remix Ide and Metamk

To better understand thisstand, let’s explore Howeworks wth MetamSk. In a Remix project, you can you through SetMessage (STR) function to establish for blockchachachachachachachaerr theor places whee messages are. Howver, wen MetamSk is it to interact the block chain, message configuration on function to differently.

Curs and problem solving

To solve problems of this problem, we will follow thees:

  • Verify the exit the Remix console: in your Remix project, go to the “Console” tab in Remix Studio (the IDE for Remix). related to Metamk.

  • Inspect the SetMessage () Getmessage () : Look at the code for both functions in ther their JavaScript Metamask. Check if there are differences between

  • Try different messages: Try to configure types of messages (for example, chains, numbers) to etmessage ().

Conclusion*

The problem is not related to underlying blockchain technology, but there with the way the MetamSk interacts the Messenger System in Remix. Despite configuring a message chain.

To solve that problem, you must inspect the code for the for the SetMessage () and Getmessage () functioning and verify that are. In addition, triy different messages to determin if thee is a problem.

Example code

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)

Gere is an example of you can you can Setmessage () function in youur Remix project:

JavaScript

Import {Message} of "Web3";

constate message = "Hello, world!"; // chain

// Establish the message use the Setmessage

Message.set ();


And here thee is a sample code fragment to configure a message theGetmessage ():

JavaScript

Import {Message} of "Web3";

import {remixcontraction} of "./remixcontraction";

constc contract = new remixcontrate ();

Contractor.setMessage (Message); // chain

In this example, we define a Message variable as a chain and the thestablish it. That’s the Getmessage () method to recover the value.

Following theese and verifying any difference theween solve that problem.
