Sonata Media Bundle Installation error - symfony

Question

'm trying to install sonata media bundle on a symfony 3.3.6
I'm folowing this doc : https://sonata-project.org/bundles/media/3-x/doc/reference/installation.html
But I have an error when i'm using this command line, to generate DB : php bin/console doctrine:schema:update --force
the error message :
[Doctrine\DBAL\DBALException] Unknown column type "json" requested.
Any Doctrine type that you use has to be registered with
\Doctrine\DBAL\Types\Type::addType(). You can get a list of all the
known types with \Doctrine\DBAL\Types\Type::getTypesMap(). If this
error occurs during database introspection then you might have forgot
to register all database types for a Doctrine Type. Use
AbstractPlatform#registerDoctrineType Mapping() or have your custom
types implement Type#getMappedDatabaseTypes(). If the type name is
empty you might have a problem with the cache or forgot some mapping
information.
my config.yml is taken from the documentation. I reviewed all such articles and nowhere can I find an answer. Why does this error occur? Help please, I'm starting to be disappointed

Answer 1

You have to add json type in your doctrine configuration:
doctrine:
dbal:
types:
json: Sonata\Doctrine\Types\JsonType
In your config file, you have doctrine section twice.
The first one is applied:
doctrine:
dbal:
driver: pdo_mysql
host: '%database_host%'
port: '%database_port%'
dbname: '%database_name%'
user: '%database_user%'
password: '%database_password%'
charset: UTF8
# if using pdo_sqlite as your database driver:
# 1. add the path in parameters.yml
# e.g. database_path: '%kernel.project_dir%/var/data/data.sqlite'
# 2. Uncomment database_path in parameters.yml.dist
# 3. Uncomment next line:
#path: '%database_path%'
orm:
auto_generate_proxy_classes: '%kernel.debug%'
naming_strategy: doctrine.orm.naming_strategy.underscore
auto_mapping: true
and you didn't define the JSON type there.
