well, for symfony 4.1 i don't really know but i downgrade symfony to 3.4 and faced the same problem and the solution is to set the mysql version in config file.

config.yaml

doctrine:
    dbal:
        ...
        server_version: "%database_server_version%"

parameters.yaml

parameters:
    ...
    database_server_version: 5.7

Looks like it could be related to PHP version. See related issue on Github.

Some potential causes / fixes:

  1. Depending on how you installed dotenv (see docs) you may need to get rid of vendor folder and run fresh composer install
  2. Downgrade to PHP 7.0 as return types introduced in 7.1 hence the error (obviously not long term solution)
