I have only FTP available ...

So you want to install Kimai v2 but have no SSH access to your server? There is a workaround available, read the additional installation instructions.

Error on bin/console doctrine:schema:create

If you get an error during the installation of the database schema that mentions DC2Type:json_array, e.g. like the following:

In PDOConnection.php line 109:

  SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'JSON
   NOT NULL COMMENT '(DC2Type:json_array)', UNIQUE INDEX UNIQ_B9AC5BCE5E237E06' at line 1

Then the most likely case is that you are using a MariaDB database which is too old. You can find out which version is used by executing mysql --version or by checking the server information e.g. with PHPMyAdmin.

There is a discussion in the issue tracker about this topic.

There are two solution for this:

• Update your MariaDB server to at least 10.7.2
• Switch to SQLite (that can be changed in your .env file)

Further readings:

• MariaDB - JSON support was added with 10.7.2
• Using JSON fields with Doctrine ORM on PostgreSQL & MySQL
