An error occurred in Solana Update Journal Entry, CRUD DApp
I am here to help you troubleshoot an issue with your Solana-based CRUD (Create, Read, Update, Delete) data application (DApp). Specifically, I will explain the error that occurred when calling the “update_journal_entry” statement from the frontend.
Error Details
The error message I received is as follows:
“An error occurred: Error: Maximum account resolution depth reached”.
This error usually occurs in Solana’s Web3.js library or other external libraries used by the DApp. Let’s take a look at the possible causes and solutions to resolve the issue.
Possible Causes
- Circular Reaches: Calling a function that resolves multiple accounts can lead to circular reaches, which can cause errors.
- Account Resolutions: The “update_journal_entry” instruction may attempt to resolve multiple accounts at once, which may result in excessive depth traversals.
- External Library Issues
: The error may be caused by external libraries used by the DApp.
Workarounds
To resolve this issue, try the following workarounds:
1. Use “maxDepth: 0” when calling “update_journal_entry”
Replace the line where you call update_journal_entry with the following:
updateJournalEntry(
journalID,
{ ... },
maxDepth : 0
);
This will prevent the DApp from attempting to traverse multiple accounts at once.
2. Use “maxDepth: -1” when calling “updateJournalEntry”
Alternatively, you can explicitly set the `maxDepth’ option:
const updateJournalEntry = ( journalId , { ... } , maxDepth ) => {
// ...
};
updateJournalEntry(
journalId,
{ ... },
maxDepth: -1
);
This will prevent the DApp from even trying to crawl multiple accounts.
3. Use a different library
If the above solutions don’t work, you might want to look at other libraries used by the DApp and see if they have any issues that are causing this error.
Additional Tips
- Make sure you are using the latest versions of the Solana Web3.js library and external libraries.
- Before calling “update_journal_entry”, make sure that all affected accounts are properly unlocked.
- If you are using a custom implementation, test it thoroughly to detect regressions.
By following these solutions, you will be able to resolve the error and continue building your Solana-based CRUD DApp. If you have any further questions or concerns, please feel free to reach out!
