Redmine

I'm upgrading Redmine 4.2.7 to 4.2.8 (docker images) and cannot view any page after user login was done on website.

Upgraded web UI renders that for me:

Internal error

An error occurred on the page you were trying to access.
If you continue to experience problems please contact your Redmine administrator for assistance.

If you are the Redmine administrator, check your log files for details about the error.

I'm using MySQL 5.7 as a database.

I have no installed plugins.

I reproduce that error on default configuration: block mapping my configuration to container.

Migrations were redone manually, as described redmineupgrade (https://www.redmine.org/projects/redmine/wiki/Redmineupgrade), step 4 & 5

Now I rolled back to 4.2.7 version, but it looks like I cannot receive any upgrade. That sounds bad.
