Fix React components that are not exported as default
React (and bundlers that target it) throws this error when you import a component as a default export but the module only exposes named exports. Align the import/export style or re-export the named symbol as the default so React actually receives the component it expects.

SQL logic error is SQLite's most generic error code, indicating a problem with your SQL query, virtual table, or internal SQLite issue. This error is difficult to debug because it lacks specificity—the actual cause could be a malformed query, corrupted virtual table, or even memory corruption in your application code.
