Error explanation: TypeError Cannot use ‘in’ operator to lookup ‘option’ in publicKey
The error message “TypeError: Cannot use ‘in’ operator to lookup ‘option’ in publicKey” indicates a problem with the code that attempts to access an element of the ‘publicKey’ object. In this case, the problem is related to the @debridge-finance/solana-transaction-parser library.
When using @debridge-finance/solana-transaction-parser, Solana’s transaction data structure is slightly different from traditional JavaScript objects. In particular, it uses a specific syntax to access and manipulate transaction properties.
The error message suggests that there is an attempt to lookup a property called “option” within the publicKey object. However, this property does not exist in Solana’s standard transaction data structure.
What is the standard data structure for Solana transactions?
In Solana, transactions are represented as JSON objects with specific fields:
blockHash: The hash of the transaction block.
blockNumber: The block number of the transaction.
timestamp: The timestamp of the transaction.
transactionId: A unique identifier for the transaction.
inputs: An array of input objects, each representing a single instruction to be executed by Solana validator nodes.
outputs: An array of output objects, each representing a single output transaction.
The publicKey object in the context of Debridge is likely a custom data structure used to store and access Solana-specific information about your project. It may contain additional fields that are not present in the standard transaction data structure.
Solution: Understand the standard transaction data structure
To resolve the error, it is necessary to understand how the publicKey object is actually structured within the Debridge Solana transaction analysis library. Unfortunately, I am a big language model and do not have direct access to the library’s documentation or source code.
However, based on your example function, it appears that you are attempting to parse a transaction with additional fields that are not present in the standard JSON object. To resolve this issue:
- Verify that the
publicKeyobject has all the necessary properties as expected by Debridge.
- If you have added custom fields specific to your project, ensure that they are defined correctly within the
publicKeyobject.
Here is an example of how you can modify your code to include some additional fields commonly found in Solana transactions:
`javascript
async function execute() {
const programId = 'your_program_id_here';
constant public key = '@debridge-finance/solana-transaction-parser';
// Define a custom transaction data structure
try {
const parsedTransaction = await @debridge-finance/solana-transaction-parser. run(
program id,
public key
);
console. log(parsedTransaction);
} catch (error) {
console. error(error);
}
}
`
Please note that this is a simplified example and you should refer to the official Debridge documentation or the@debridge-finance/solana-transaction-parserlibrary documentation for more detailed information about your custom transaction data structure.
Additional Tips:
- Make sure that your project'ssolana.json
file contains all the necessary properties defined by Solana.
- Make sure you have added all required fields to thepublicKey` object according to Debridge specifications.
