CI4 launches web development app only on its current release and rework — refactor set on the stage. On Docker environment it’s OK up until an error stack trace is cast.

docker pull veritus4/lamp-docker:php-mysql

is the latest version of more or less standard — compared to other LAMP provision packs in the market — open SUSE based image.

The point is that

docker container exec -it 9ee22a6ebdce /bin/bash
php spark spotify:grant

is passed and then

php spark spotify:access

is triggering erroneous behavior:

CodeIgniter CLI Tool - Version 4.0.0-rc.3 - Server-Time: 2021-01-01 14:40:06pm

It is obvious that this PHP versions, available in virtual Docker container — machine are limited to PHP7, whereas the CI4 framework is requiring adapted non deprecation errors casting behavior and versions — CI4 is referencing MVC.
