How It Affects Your App
The error ER_INVALID_JSON_CHARSET indicates that the character set used for the JSON data is not supported by MySQL. This can cause the application to fail to store or retrieve data from the database, resulting in unexpected behavior or errors. It can also lead to data corruption or data loss, as the application may not be able to properly interpret the data. In addition, the application may be unable to properly process queries or commands, leading to further errors.
How To Fix
1. Check the error log for the MySQL 3144 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 3144 error is gone:
$ tail -f /var/log/mysql/error.log
6. Use an automated database observability tool to monitor and fix the MySQL 3144 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 fix any issues that arise. They can also provide detailed metrics and logs that can help you diagnose and troubleshoot any issues that may arise.
