Solved: The Solana Blink Operation Error when signing the non -Stanarde Transactions of the Anchor Program
As a programmer working to combine the non -standard effect on your own program for before, you are probably not foreign to Solan’s complexity. Recently, I came across a mistake by signing a non -standard transaction of anchoring program with a trainee action. In this article, I go through what can be caused by a problem and I give a solution to the step -in step.
Error: Unexpected Error
When starting the next code you will come across the following error:
`Salt
I have an error error: an unexpected error
Xe <e
This error usually indicates that the transaction signing procedure has encountered an unexpected problem during the phase of checking the correctness of the anchor program. The exact cause of this error can be difficult to indicate without much context.
Possible causes and solutions
There are several potential causes of this error, including:
- Neat or missing with Achotative contract : Be sure to check that your custom contract of the Sidre program is correctly implemented with the necessary code.
- Misdemeanor Verification Rules : Make sure the validation rules in the Anchor Program Agreement are corresponding to those stated in the CLI Solana CO documentation or anchor program.
- Failure in the correctness of the input data : Make sure all the required entry values are given when signing transactions, according to the rules of verification of correctness.
To solve this problem, try the following steps:
Step 1: Check the implementation of the Sidre Contract Program
Twice to make sure the contract with the non -state of the anchorage is correctly implemented by the necessary code and metadaths (eg „id“, „name“, etc.). Be sure to check the contract implementation function restore an important transaction.
`Javascript
Const implementation = requires ("@solan/web3.js"). implementation;
Const anchorprogram = wait for implementation
Const implementationTransation = wait for anchorprogram_depeloytransaction ({{{{{{{{{{{{{{
ID: YourContract_id,
Name: "Your Name of the Agreement",
// Add other necessary metapodate ...
});
Step 2: Check validation rules
Make sure that the principles of validation in the contract for anchoring those stated in the Solana CLI program or the anchor program listed in the documentation are responsible. You can check this by examining the „validate“ function.
`Javascript
Const Validate = Async (TX, Programidmid) => {
// Check your input values here ...
if (! tx.Amount ||! tx.signedby) {) {
Stop with a new mistake ("Incorrect entry of verification of correctness");
Iche
};
Step 3: Check the entry to sign transactions
Make sure all necessary entry values are provided when signing transactions. You can check this by checking the transactions metadators.
`Javascript
Const TX = Wait anchorprogram_signtransation ({{{{{{{{{{{{
ID: YourContract_id,
Program,
amount,
Signed,
// Other required properties ...
});
If you have checked that these steps solve the problem, you should no longer meet the „Unexpected Error“ message. However, if you experience mistakes after trying these corrections, give more details about the code and environment for further assistance.

Signing a non -stomantic transaction of anchoring program with blinking actions can be a difficult task. By checking whether the contract implementation is correct, checking the validation rules and ensure that all the input values required are provided when signing transactions, you should be able to solve all the problems that occur during this procedure. If you still have problems after trying these steps, contact further tips or support.
