How It Affects Your App
The impact of MySQL 3146 ER_INVALID_TYPE_FOR_JSON on an application is that it prevents the application from storing or retrieving data in a JSON format. This can cause data to be stored or retrieved incorrectly, leading to unexpected results or errors. It can also prevent the application from functioning properly, as it may rely on JSON data to operate. In addition, it can lead to data loss or corruption, as the application may not be able to store or retrieve the data correctly.
How To Fix
1. Check the error log for the MySQL 3146 error:
$ tail -f /var/log/mysql/error.log
2. Check the MySQL configuration file for the max_allowed_packet setting:
$ grep max_allowed_packet /etc/mysql/my.cnf
3. Increase the max_allowed_packet setting to a higher value:
max_allowed_packet = 16M
4. Restart the MySQL server:
$ sudo service mysql restart
5. Check the error log again to make sure the MySQL 3146 error is gone:
$ tail -f /var/log/mysql/error.log
6. Use an automated database observability tool to monitor and fix the MySQL 3146 in question. Automated database observability tools can provide real-time insights into the performance and health of your database, allowing you to quickly identify and address any issues that arise.
