Error updating database: Executor was closed - Troubleshooting Guide

This error message suggests that there was an issue updating the database due to the executor being closed. The executor is responsible for executing SQL statements and interacting with the database.\n\nThere are a few possible reasons for this error:\n\n1. The executor was closed manually by the developer: Check your code to ensure that you are not closing the executor prematurely. Make sure that the executor is properly initialized and closed at the appropriate times.\n\n2. Connection timeout or loss: If the connection to the database is lost or times out while the executor is in use, it might result in this error. Check your database connection settings and try reconnecting to the database.\n\n3. Concurrent access to the executor: If multiple threads or processes are trying to access the executor simultaneously, it can lead to conflicts and result in the executor being closed. Ensure that you are properly synchronizing access to the executor to prevent concurrent access issues.\n\nIn order to resolve this issue, you will need to identify the root cause of the problem based on the above possibilities and take appropriate action to fix it.
