How to resolve the error : COLLATION 'utf8_general_ci' is not valid for CHARACTER SET 'latin1' mysql verision 8.0.0 (docker,django,datagrip)

I am trying to use datagrip for my database management. I can create a connection but when the data of the database I get this error:

[42000][1253] COLLATION 'utf8_general_ci' is not valid for CHARACTER SET
 'latin1'. COLLATION 'utf8_general_ci' is not valid for CHARACTER SET 'latin1'

I have looked only for solutions to this but non of them seem to work. A few of them involved changing the /etc/mysql/my.cnf file it showed the changes that should work but didn't have any effect.

my.cnf:

!includedir /etc/mysql/conf.d/
!includedir /etc/mysql/mysql.conf.d/
[client]
loose-default-character-set=utf8

[mysql]
default-character-set=utf8

[mysqld]
collation-server = utf8_unicode_ci
init-connect='SET NAMES utf8'
character-set-server = utf8

the result:

show variables like '%char%';
