Solana: An Error Occured: Error: Reached maximum depth for account resolution

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 am resolving the error that occurred when calling the update_journal_entry instruction from the UI.

Error Details

The error message you received is:

An error occurred: Error: Maximum depth for account resolution reached

This error usually 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 Accesses: When calling a function that resolves multiple accounts, it can lead to circular accesses and cause errors.

• Account Resolution: The update_journal_entry instruction may attempt to resolve multiple accounts at once, resulting in excessive depth traversals.

• External Library Issues: The external library used by your DApp may cause the error.

Workarounds

To resolve this issue, you can try the following workarounds:

1. Use maxDepth: 0 when calling update_journal_entry

Replace the line where you call 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 explicitly set the maxDepth option:

const updateJournalEntry = (journalId, { ... }, maxDepth) => {
// ...
};
updateJournalEntry(
journalId,
{ ... },
maxDepth: -1
);

This prevents your DApp from trying to traverse multiple accounts.

3. Use a different library

If the above solutions don’t work, it’s worth investigating other libraries used by your DApp and checking if there are any issues that are causing this error.

Additional Tips

• Make sure you’re using the latest versions of Solana’s Web3.js library and external libraries.

• Make sure all associated accounts are properly resolved before calling update_journal_entry.

• If you are using a custom implementation, be 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 more questions or concerns, feel free to ask!
