Error 2020: Got packet bigger than 'max_allowed_packet' bytes when dumping table
When a MySQL client or the mySQL server gets a packet that is larger than the max_allowed_packet bytes, it throws error and closes the connection. We can increase the value temporarily for taking mysqldump.
#mysqldump --max_allowed_packet=512M database > database.sql
Here we need to replace the required database name. Please note that this configuration is temporary.
