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: Despite successful news setting, the transaction cannot add to blockchain

As a development, it is frustrating if you cannot carry out uncomplicated action, only to find out later in this article,

The problem: Set a message via remix ide

When working, this method is used to store data that are displayed in the blockchain of Explorer or in other places where messages are displayed. The problem occurs when an attempt is made to use this function with metamask.

The problem: Despite successful news setting, the transaction cannot be added

When calling up the «SetMessage ()function, surprisingly, however, no error message is not displayed in the blockchain explorer or in other places where messages are displayed. If we try to call up the message using the "GetMessage () ' Also determine that no value is returned.

To better understand this problem, let us examine how Remix works with Metamask.Function to determine data for blockchain explorer or to other places where messages are displayed. However, when using metamask for interaction with the blockchain, the functional functionality of the news setting seems to work differently.

Debugging and troubleshooting

To fix this problem, we follow the following steps:

1.

• Check whether there are differences between the two methods such as asynchronous behavior or error treatment.

3.

Diploma

The problem is not related to the underlying blockchain technology, but how Metamask interacts with the messaging system in the remix. Function, no error message or transaction protocol is displayed when metamask interacts with the blockchain.

And» GetMessage () and" Getmessage ()Functions and make sure that they work as expected. Also test different messages to determine whether there is a certain type of data that triggers the problem.

Example code

Here is an example of how you could use the «SetMessage ()function in your remix project:

JavaScript

{Message} import from «web3»;

Const Message = «Hello, world!»; // string

// Use the message with the set measurement function

message.set ();

`

Getmessage:

JavaScript

{Message} import from «web3»;

Import {remixcontract} from «./Remixcontract»;

Const contract = new remixconcontract ();

Contract.Setmessage (message); // string

`

Function for setting. We then call the method "GetMessage () to access the value.

And" GetMessage ()and» GetMessage () `Functions in your Metamask -JavaScript module should be able to diagnose and fix this problem.
