Error Occurred in Solana Update Journal Entry CRUD DApp
I’m here to help you troubleshoot an issue with your Solana-based CRUD (Create, Read, Update, Delete) Data Application (DApp). Specifically, I’ll address the error that occurred when calling the update_journal_entry instruction from the UI.
Error Details
The error message you received is:
An Error Occured: Error: Reached maximum depth for account resolution
This error typically occurs in Solana’s Web3.js library or other external libraries used by your DApp. Let’s dive into the possible causes and solutions to resolve this issue.
Possible Causes
- Circular Reaches: When calling a function that resolves multiple accounts, it can lead to circular reaches, causing errors.
- Account Resolutions: The
update_journal_entryinstruction may attempt to resolve multiple accounts simultaneously, resulting in excessive depth traversals.
- External Library Issues: External libraries used by your DApp might be causing the error.
Solutions
To resolve this issue, you can try the following solutions:
1. Use maxDepth: 0 when calling update_journal_entry
Replace the line where you’re calling update_journal_entry with:
updateJournalEntry(
journalId,
{ ... },
maxDepth: 0
);
This will prevent your DApp from attempting to traverse multiple accounts at once.
2. Use maxDepth: -1 when calling updateJournalEntry
Alternatively, you can set the maxDepth option explicitly:
const updateJournalEntry = (journalId, { ... }, maxDepth) => {
// ...
};
updateJournalEntry(
journalId,
{ ... },
maxDepth: -1
);
This will prevent your DApp from attempting to traverse multiple accounts at all.
3. Use a Different Library
If the above solutions don’t work, it may be worth investigating other libraries used by your DApp and checking if they have any issues causing this error.
Additional Tips
- Make sure you’re using the latest versions of Solana’s Web3.js library and external libraries.
- Ensure that all accounts involved are properly resolved before calling
update_journal_entry.
- If you’re using a custom implementation, make sure to test it thoroughly to catch any regressions.
By following these solutions, you should be able to resolve the error and continue building your Solana-based CRUD DApp. If you have any further questions or concerns, feel free to ask!
