2.6.1 to 2.7 Database Update Error

[empmdk]

I'm getting the following error when trying to update a local copy for testing.

ALTER TABLE app_entity_42 CHANGE `field_615` `field_615` text CHARACTER SET utf8mb4 NOT NULL
2006
MySQL server has gone away

field_615 is a "Users" field type. I have 3 other entities with that same field & configuration. I've only seen app_entity_42 cause this so far. I do get the "OK" check mark next to each entity though. Not sure if the message is something that can be ignored.

Jut run this update script again /install/autoupdate/data_prepare_from_2.6_to_2.7.php

I did try running it a few more times to see if it would fix the error but it shows up each time.

It means there are not enough resources to update database to utf8mb4
You can ignore it for now.
