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

An error occurred in Solana CRUD DApp update journal entry

I am here to help you troubleshoot your Solana-based CRUD (Create, Read, Update, Delete) data application (DApp). Specifically, I will address the error that occurred when calling the update_journal_entry command from the UI.

Error Details

The error message you received is:

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 your DApp. Let’s look at the possible causes and solutions for this issue.

Possible Causes

• Circular Scopes: When calling a function that resolves multiple accounts, this can lead to circular scopes that cause errors.

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

• External Library Issues: The error may be caused by external libraries used by your DApp.

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 iterate through multiple accounts at once.

2. Use maxDepth: -1 when calling updateJournalEntry

You can also explicitly set the maxDepth option:

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

This will prevent your DApp from trying to traverse multiple accounts.

3. Use a different library

If the above solutions don’t work, it might be helpful to look at other libraries used by your DApp and check if they have issues causing this error.

Additional Tips

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

• Make sure all affected accounts are resolved correctly before calling update_journal_entry.

• If you are using your own implementation, be sure to thoroughly regression test it.

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!
