SOLANA Candy Machine Machine: I can’t read properties of non -healized
As a developer working on a Solana project, you may have encountered problems with Solana candy. A common mistake it can occupy is when interacting with the MINT button. In this article we will deepen the cause of the problem and provide a solution.
Error: I can’t read properties of indefinitely
The message of the error “Unable to read the non -operated properties” shows a problem when attempting to access the object of a ‘neophyte’ property. This can happen in various scenarios where you are trying to use a feature or method that is not properly initialized or imported.
In the case of Solana’s candy machine, this error usually occurs when clicking on the MINT button and you are trying to extract the value _bn. The variable _bn is probably used as a substitute for actual value, but it is set.
Causes of error
Here are some possible reasons that can lead to this error:
- Inadequate initialization : Make sure you initialize all the necessary features and variables before trying to access them.
- Missing imports or dependencies
: Check that you have imported the necessary libraries and modules, including the “Sollana Program” and its sub-hummarks (eg, “candy-machine”).
- Improper use of features or methods : Make sure you use the functions or methods properly and in the range where they are defined.
Decisions
To resolve this problem, try the following steps:
- Check for missing import : Check that all necessary imports have been added to your code.
- Check the initialization of the feature : Make sure all the features or methods you are trying to use are properly initialized and set up before trying to access them.
- Check variable declarations : double check that all variables declared in range where they can be used are actually assigned values.
Sample code
Here is an example of how a coin button can be realized in solidity:
`Solidness
Pragma Solidity ^0.8.0;
Contract Candymachine {
Uint256 Public _BN; // variable to store value _bn
Mint Function (Uint256 sum) publicly {
// Initialize the variable _bn in this range
_bn = 42;
// Now you can use the _bn variable without errors
console.log (_bn); // Output: 42
}
}
`
In this exam, we initialized a global variable public _bn in the mint function. This guarantees that when we try to access `_bn later in another part of the code, it is properly set.
Following these steps and checking your code for any potential problems, you should be able to solve the error “Can’t read the properties of the indefinite” error associated with the Solana candy machine. If the problem continues, do not hesitate to provide more details about your project and I will do my best to help you further!
