How It Affects Your App
MySQL 3142 ER_INVALID_JSON_BINARY_DATA indicates that the data stored in the database is not valid JSON binary data. This can have a significant impact on an application as it may prevent the application from accessing the data it needs to function properly. It can also lead to unexpected errors and unexpected behavior in the application. In addition, it can lead to data corruption and data loss if the application is not able to properly handle the invalid data.
How To Fix

$ 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 3142 error is gone:
$ tail -f /var/log/mysql/error.log
