Greetings.

I am trying a migration from version

liferay-ce-portal-7.3.7-ga8

to

liferay-ce-portal-7.4.3.112-ga112.

I execute the script: …/liferay-ce-portal-7.4.3.112-ga112/tools/portal-tools-db-upgrade-client/db_upgrade.sh

It seems to work fine, except for a couple of logs:

Errors

------

However, upon navigating to the home page in a web browser, I get a blank page with the message “Unexpected System Error”. In the Catalina log file I get the following error

2024-06-20 14:16:55.255 ERROR [http-nio-8080-exec-7][error_jsp:551] User ID null, current URL /web/guest/home, referer null, remote address 192.168.67.239, null exception

I found a similar question asked here: https://liferay.dev/ask/questions/portal/error-on-upgrade-ga99-to-ga100-user-id-null-current-url-referer-null

In my database, the default user was already in active status.

I would appreciate any suggestions.

Thank you in advance.
